description Publicationkeyboard_double_arrow_right Part of book or chapter of book 2009 FrancePublisher:Springer Berlin Heidelberg Authors: Leigh H. Royden; Laurent Husson;Leigh H. Royden; Laurent Husson;Temporal variations in the buoyancy of subducting lithosphere exert a fi rst-order control on subduction rate, slab dip and the position of the associated volcanic arc. We use a semi-analytic, three-dimensional subduction model to simulate unforced subduction, in which trench motion is driven solely by slab buoyancy. Model rates of subduction and model slab dip respond almost immediately to changes in the buoyancy of the subducting lithosphere entering the trench; as more buoyant slab segments correlate with slower subduction rates and steeper slab dip. The results are largely consistent with observations from the Banda and southern Apennine subduction systems, where subduction slowed and ended shortly after the entry of continental lithosphere into the trench. Over a 2 m.y. period, model subduction rates decrease from ̃70 mm/year to ̃30 mm/year for the Banda Arc, and from ̃40 mm/ year to ̃20 mm/year for the Apennine Arc. Increases in model slab dip and decreases in arc-trench distance are likewise consistent with hypocenter locations and volcanic arc position along the Banda and Sunda arcs. In contrast, a time period of ̃10 m.y. is needed for model subduction rates to slow to near zero, much longer than the ̃3 m.y. upper bound on the observed slowing and cessation of trench motion in the Apennine and Banda systems. One possible explanation is that slab break-off, or the formation of large slab windows, occurred during the last stages of subduction, eliminating toroidal fl ow around the slab and allowing the slab to steepen rapidly into its final position

There have been three main episodes of volcanic activity since the Miocene, separated by long periods of quiescence. The lava fl ows and domes were emitted along lithosphere-scale fault zones. With its famous scenery, the Atakor massif is one of the largest (2150 km 2 ) volcanic districts of the province. Mafi c volcanic rocks are abundant in the center of the massif, but become scarce to the south, where only few scarps are observed. Phonolites occur only in the Assekrem area, whereas trachytes occur everywhere, with a marked enrichment in quartz to the south and the southeast (Tahifet area), where rhyolites are also exposed. Two magmatic groups have been identifi ed based on fi eld and petrological observations. The mafi c group has a basanite-phonotephrite association, forming uplifted plateaus, scoria cones, and valley-fi lling lava fl ows. The presence of mantlederived amphibole ± biotite megacrysts and peridotite mantle xenoliths together with the nonprimary chemical compositions of the magmatic rocks suggest that magmatic differentiation may have occurred within the upper mantle. The felsic group is composed of two diverging trends, a silica-saturated benmoreite-trachyte-rhyolite trend and a silica-undersaturated trachyte-phonolite trend. The primary magmas are considered to have been produced as a consequence of lithospheric mantle delamination along linear megashear zones inducing low degrees of decompression partial melting at variable depths (110–40 km) in the upwelling asthenosphere. The discrete volcanic episodes correspond to periods of reactivation of the major fault zones in response to discrete Neogene extensional tectonic events associated with Alpine orogenesis in the Western Mediterranean region induced by Africa-Eurasia collision.

The evidence for past and present water on Mars has been a main driver of its exploration. Ancient fluvial landforms indicate that Mars once had surficial conditions suitable for the presence of persistent liquid water on its surface. However, climate models of early Mars remain notably difficult to reconcile with these observations. The global inventory of water on Mars is critical to understanding how the planet's potential habitability has varied over time. In this chapter, we review these topics, including the inventory of water, its various reservoirs, and potential loss mechanisms, and discuss how the planet’s hydrosphere evolved with time.

The hole was initiated during ODP Leg 206 and lengthened during Integrated Ocean Drilling Program Expeditions 309, 312, and 335. Nine samples were analyzed from two gabbroic sections (Gabbros 1 and 2) recovered from Expedition 312 for crystallographic-preferred orientation of plagioclase, clinopyroxene, olivine, and orthopyroxene. Plagioclase and clinopyroxene are the focus of this study because these two phases are the most modally abundant minerals. Our results are compared with shape-preferred orientations from the same samples. The results demonstrate the absence of crystallographic-preferred orientation in any phases analyzed. Even though the nature of the sheeted dike/gabbro transition zone is still poorly constrained, our results are similar to those reported in rocks that have been interpreted to represent the crystallized axial melt lens in the Oman ophiolite.

We do not restrict the review to Cassini 's results, as past and current ground-based or Earth-based observations are still fundamental to draw a complete picture of the planet. We address the global composition and its importance in studying the origin of the planet, and the meridional and vertical gradients in composition, stressing their insights into Saturn 's dynamics. We present the current 1D thermochemical and photochemical models, how these models fare to reproduce the observed composition, and the first attempts to design 2D chemical models. We present some directions to improve our knowledge of Saturn 's composition both from observations, modelling and laboratory experiments.

Most fossil evidence on-land is Early Pleistocene in age, and occurs in peninsular Italy, Sicily and on some Greek islands, whilst submerged situations are by large late Pleistocene. According to circumstances, the mode of preservation of fossil cold-water coral varies sensibly (from loose corals to micritic limestones) what affects the level of confidence of the paleoecological reconstruction. All known situations point about a bathyal setting for such cold-water coral hosting deposits in the Mediterranean basin, but under many respects the geological record of cold-water coral paleoenvironments is yet largely underworked. Research developments are discussed, with special emphasis on the widespread submarine occurrences which prevail over the on-land cold-water coral legacy.

In this study, we present new detrital zircon fission-track data of sediment samples from eight Italian rivers, draining the European Alps and previously published data from the Rhône delta in southeastern France. These samples are used to demonstrate that variable etching rates in detrital zircon, which have been shown elsewhere to necessitate a multi-etch procedure during sample preparation, are not a significant problem for zircons from the Alps. Etching response in zircon is a function of radiation damage, principally caused by α-decay. Spontaneous fission-track density can be used as a proxy for total radiation damage. We use spontaneous track density, fission-track cooling age, and uranium content to define a “window of countability” for detrital zircon. We also show that detrital zircon fission-track results are reproducible, by comparing results from modern sediments from the same river drainage. The results also compare well with the known distribution of bedrock cooling ages in each drainage. On a regional scale, our data illustrate that a few samples can provide an overview of the fission-track age pattern of a whole orogen, which is useful for exhumation and provenance studies.

Mathias Kondolf; Hervé Piégay; Laurent Schmitt; David R. Montgomery;G. Mathias Kondolf; Hervé Piégay; Laurent Schmitt; David R. Montgomery;This chapter discusses general philosophies of classifications in fluvial geomorphology, and reviews examples of geomorphic classification systems. It explores uses and limitations of classifications as a tool in fluvial geomorphology and river management. Buffington and Montgomery emphasize the distinction between descriptive and process‐based classifications, noting that descriptive classifications can be quantitative and process‐based classifications can be qualitative. Distinctions between mountain torrents and lowland rivers are perhaps the oldest form of river classification. A wide range of geomorphic river classification schemes have been proposed since the late 19th century, reflecting the diversity of environmental settings, the variety of potential approaches to ordering complex natural systems, the intellectual framework of the field and the diverse purposes for which the systems were developed. Classification can focus on spatial features such as river patterns, floodplains, in‐channel features, which can be separated according to a set of parameter. International audience deuxième édition

Parsons; Ricardo Silva Jacinto; Ronan Apprioual;Turbidity currents transport globally significant volumes of sediment and organic carbon into the deep-sea and pose a hazard to critical infrastructure. Despite advances in technology, their powerful nature often damages expensive instruments placed in their path. These challenges mean that turbidity currents have only been measured in a few locations worldwide, in relatively shallow water depths (,,2 km). Here, we share lessons from recent field deployments about how to design the platforms on which instruments are deployed. First, we show how monitoring platforms have been affected by turbidity currents including instability, displacement, tumbling and damage. Second, we relate these issues to specifics of the platform design, such as exposure of large surface area instruments within a flow and inadequate anchoring or seafloor support. Third, we provide recommended modifications to improve design by simplifying mooring configurations, minimizing surface area and enhancing seafloor stability. Finally, we highlight novel multi-point moorings that avoid interaction between the instruments and the flow, and flow-resilient seafloor platforms with innovative engineering design features, such as feet and ballast that can be ejected. Our experience will provide guidance for future deployments, so that more detailed insights can be provided into turbidity current behaviour, in a wider range of settings.

Gardner, James; Burgisser, Alain; Hort, Matthias; Rutherford, Malcolm;E. Gardner, James; Burgisser, Alain; Hort, Matthias; Rutherford, Malcolm;Surface volcanic gases may reflect volatile budgets of magma and forecast impending eruptions, and their release to the atmosphere may affect climate. The dynamics of magma degassing is complicated, however, by differences in the solubility, partitioning, and diffusion of the various volatiles, all of which can vary with pressure, temperature, and melt composition. To constrain possible gas outputs, we carried out experiments to determine how Cl partitions between water bubbles and silicate melt, and decompression experiments to examine how Cl behaves during closed- and open-system degassing. We incorporate our findings and those from the literature for CO2 and S into a steady, isothermal, and homogeneous flow model to estimate fluxes of gases at the vent from ascending water-rich magma, assuming different scenarios for the onset and development of permeability in bubbly magma. We find that, for given permeability scenarios, total gas fluxes vary with magma flux, but ratios of gas species do not change. The S/Cl and SO2/CO2 ratios do change, however, depending on whether the magma is oxidized or reduced. After magma fragments into a Plinian eruption column gases continue to escape from cooling pumice in the plume, but here the rate of gas release is controlled by diffusion, which varies with temperature. Degassing of pumice and ash was modeled by linking a steady-state plume model, which gives the vertical variation of mean temperature and velocity of particles inside the plume, to a conductive cooling model of pumices, which controls diffusion of Cl, CO2, and S in pumice. We find that gas loss increases with column height (mass flux) and initial temperature, because in both cases pumices cool over a longer time period, allowing more gas to diffuse out of the matrix glass. The amount of gas released also depends on the size distribution of particles in the erupting mixture, with less being released for a finely skewed distribution.

description Publicationkeyboard_double_arrow_right Part of book or chapter of book 2009 FrancePublisher:Springer Berlin Heidelberg Authors: Leigh H. Royden; Laurent Husson;Leigh H. Royden; Laurent Husson;Temporal variations in the buoyancy of subducting lithosphere exert a fi rst-order control on subduction rate, slab dip and the position of the associated volcanic arc. We use a semi-analytic, three-dimensional subduction model to simulate unforced subduction, in which trench motion is driven solely by slab buoyancy. Model rates of subduction and model slab dip respond almost immediately to changes in the buoyancy of the subducting lithosphere entering the trench; as more buoyant slab segments correlate with slower subduction rates and steeper slab dip. The results are largely consistent with observations from the Banda and southern Apennine subduction systems, where subduction slowed and ended shortly after the entry of continental lithosphere into the trench. Over a 2 m.y. period, model subduction rates decrease from ̃70 mm/year to ̃30 mm/year for the Banda Arc, and from ̃40 mm/ year to ̃20 mm/year for the Apennine Arc. Increases in model slab dip and decreases in arc-trench distance are likewise consistent with hypocenter locations and volcanic arc position along the Banda and Sunda arcs. In contrast, a time period of ̃10 m.y. is needed for model subduction rates to slow to near zero, much longer than the ̃3 m.y. upper bound on the observed slowing and cessation of trench motion in the Apennine and Banda systems. One possible explanation is that slab break-off, or the formation of large slab windows, occurred during the last stages of subduction, eliminating toroidal fl ow around the slab and allowing the slab to steepen rapidly into its final position

There have been three main episodes of volcanic activity since the Miocene, separated by long periods of quiescence. The lava fl ows and domes were emitted along lithosphere-scale fault zones. With its famous scenery, the Atakor massif is one of the largest (2150 km 2 ) volcanic districts of the province. Mafi c volcanic rocks are abundant in the center of the massif, but become scarce to the south, where only few scarps are observed. Phonolites occur only in the Assekrem area, whereas trachytes occur everywhere, with a marked enrichment in quartz to the south and the southeast (Tahifet area), where rhyolites are also exposed. Two magmatic groups have been identifi ed based on fi eld and petrological observations. The mafi c group has a basanite-phonotephrite association, forming uplifted plateaus, scoria cones, and valley-fi lling lava fl ows. The presence of mantlederived amphibole ± biotite megacrysts and peridotite mantle xenoliths together with the nonprimary chemical compositions of the magmatic rocks suggest that magmatic differentiation may have occurred within the upper mantle. The felsic group is composed of two diverging trends, a silica-saturated benmoreite-trachyte-rhyolite trend and a silica-undersaturated trachyte-phonolite trend. The primary magmas are considered to have been produced as a consequence of lithospheric mantle delamination along linear megashear zones inducing low degrees of decompression partial melting at variable depths (110–40 km) in the upwelling asthenosphere. The discrete volcanic episodes correspond to periods of reactivation of the major fault zones in response to discrete Neogene extensional tectonic events associated with Alpine orogenesis in the Western Mediterranean region induced by Africa-Eurasia collision.

The evidence for past and present water on Mars has been a main driver of its exploration. Ancient fluvial landforms indicate that Mars once had surficial conditions suitable for the presence of persistent liquid water on its surface. However, climate models of early Mars remain notably difficult to reconcile with these observations. The global inventory of water on Mars is critical to understanding how the planet's potential habitability has varied over time. In this chapter, we review these topics, including the inventory of water, its various reservoirs, and potential loss mechanisms, and discuss how the planet’s hydrosphere evolved with time.

The hole was initiated during ODP Leg 206 and lengthened during Integrated Ocean Drilling Program Expeditions 309, 312, and 335. Nine samples were analyzed from two gabbroic sections (Gabbros 1 and 2) recovered from Expedition 312 for crystallographic-preferred orientation of plagioclase, clinopyroxene, olivine, and orthopyroxene. Plagioclase and clinopyroxene are the focus of this study because these two phases are the most modally abundant minerals. Our results are compared with shape-preferred orientations from the same samples. The results demonstrate the absence of crystallographic-preferred orientation in any phases analyzed. Even though the nature of the sheeted dike/gabbro transition zone is still poorly constrained, our results are similar to those reported in rocks that have been interpreted to represent the crystallized axial melt lens in the Oman ophiolite.

We do not restrict the review to Cassini 's results, as past and current ground-based or Earth-based observations are still fundamental to draw a complete picture of the planet. We address the global composition and its importance in studying the origin of the planet, and the meridional and vertical gradients in composition, stressing their insights into Saturn 's dynamics. We present the current 1D thermochemical and photochemical models, how these models fare to reproduce the observed composition, and the first attempts to design 2D chemical models. We present some directions to improve our knowledge of Saturn 's composition both from observations, modelling and laboratory experiments.

Most fossil evidence on-land is Early Pleistocene in age, and occurs in peninsular Italy, Sicily and on some Greek islands, whilst submerged situations are by large late Pleistocene. According to circumstances, the mode of preservation of fossil cold-water coral varies sensibly (from loose corals to micritic limestones) what affects the level of confidence of the paleoecological reconstruction. All known situations point about a bathyal setting for such cold-water coral hosting deposits in the Mediterranean basin, but under many respects the geological record of cold-water coral paleoenvironments is yet largely underworked. Research developments are discussed, with special emphasis on the widespread submarine occurrences which prevail over the on-land cold-water coral legacy.

In this study, we present new detrital zircon fission-track data of sediment samples from eight Italian rivers, draining the European Alps and previously published data from the Rhône delta in southeastern France. These samples are used to demonstrate that variable etching rates in detrital zircon, which have been shown elsewhere to necessitate a multi-etch procedure during sample preparation, are not a significant problem for zircons from the Alps. Etching response in zircon is a function of radiation damage, principally caused by α-decay. Spontaneous fission-track density can be used as a proxy for total radiation damage. We use spontaneous track density, fission-track cooling age, and uranium content to define a “window of countability” for detrital zircon. We also show that detrital zircon fission-track results are reproducible, by comparing results from modern sediments from the same river drainage. The results also compare well with the known distribution of bedrock cooling ages in each drainage. On a regional scale, our data illustrate that a few samples can provide an overview of the fission-track age pattern of a whole orogen, which is useful for exhumation and provenance studies.

Mathias Kondolf; Hervé Piégay; Laurent Schmitt; David R. Montgomery;G. Mathias Kondolf; Hervé Piégay; Laurent Schmitt; David R. Montgomery;This chapter discusses general philosophies of classifications in fluvial geomorphology, and reviews examples of geomorphic classification systems. It explores uses and limitations of classifications as a tool in fluvial geomorphology and river management. Buffington and Montgomery emphasize the distinction between descriptive and process‐based classifications, noting that descriptive classifications can be quantitative and process‐based classifications can be qualitative. Distinctions between mountain torrents and lowland rivers are perhaps the oldest form of river classification. A wide range of geomorphic river classification schemes have been proposed since the late 19th century, reflecting the diversity of environmental settings, the variety of potential approaches to ordering complex natural systems, the intellectual framework of the field and the diverse purposes for which the systems were developed. Classification can focus on spatial features such as river patterns, floodplains, in‐channel features, which can be separated according to a set of parameter. International audience deuxième édition

Parsons; Ricardo Silva Jacinto; Ronan Apprioual;Turbidity currents transport globally significant volumes of sediment and organic carbon into the deep-sea and pose a hazard to critical infrastructure. Despite advances in technology, their powerful nature often damages expensive instruments placed in their path. These challenges mean that turbidity currents have only been measured in a few locations worldwide, in relatively shallow water depths (,,2 km). Here, we share lessons from recent field deployments about how to design the platforms on which instruments are deployed. First, we show how monitoring platforms have been affected by turbidity currents including instability, displacement, tumbling and damage. Second, we relate these issues to specifics of the platform design, such as exposure of large surface area instruments within a flow and inadequate anchoring or seafloor support. Third, we provide recommended modifications to improve design by simplifying mooring configurations, minimizing surface area and enhancing seafloor stability. Finally, we highlight novel multi-point moorings that avoid interaction between the instruments and the flow, and flow-resilient seafloor platforms with innovative engineering design features, such as feet and ballast that can be ejected. Our experience will provide guidance for future deployments, so that more detailed insights can be provided into turbidity current behaviour, in a wider range of settings.

Gardner, James; Burgisser, Alain; Hort, Matthias; Rutherford, Malcolm;E. Gardner, James; Burgisser, Alain; Hort, Matthias; Rutherford, Malcolm;Surface volcanic gases may reflect volatile budgets of magma and forecast impending eruptions, and their release to the atmosphere may affect climate. The dynamics of magma degassing is complicated, however, by differences in the solubility, partitioning, and diffusion of the various volatiles, all of which can vary with pressure, temperature, and melt composition. To constrain possible gas outputs, we carried out experiments to determine how Cl partitions between water bubbles and silicate melt, and decompression experiments to examine how Cl behaves during closed- and open-system degassing. We incorporate our findings and those from the literature for CO2 and S into a steady, isothermal, and homogeneous flow model to estimate fluxes of gases at the vent from ascending water-rich magma, assuming different scenarios for the onset and development of permeability in bubbly magma. We find that, for given permeability scenarios, total gas fluxes vary with magma flux, but ratios of gas species do not change. The S/Cl and SO2/CO2 ratios do change, however, depending on whether the magma is oxidized or reduced. After magma fragments into a Plinian eruption column gases continue to escape from cooling pumice in the plume, but here the rate of gas release is controlled by diffusion, which varies with temperature. Degassing of pumice and ash was modeled by linking a steady-state plume model, which gives the vertical variation of mean temperature and velocity of particles inside the plume, to a conductive cooling model of pumices, which controls diffusion of Cl, CO2, and S in pumice. We find that gas loss increases with column height (mass flux) and initial temperature, because in both cases pumices cool over a longer time period, allowing more gas to diffuse out of the matrix glass. The amount of gas released also depends on the size distribution of particles in the erupting mixture, with less being released for a finely skewed distribution.
