In this work the central area of Corsica island was studied in order to reconstruct tectono-metamorphic history continental and oceanic high pressure units that occupy structurally deeper levels tectonic stacking Alpine their stratigraphic structural relationship with European margin (Hercynian Corsica). The study includes geological mapping, mesoscale microscale analysis, acquisition chemical ...

Passive continental margin subsidence is initiated by the synrift mechanical stretching of the lithospheric upper brittle layer and continues during the postrift phase; the thermal cooling and contraction of the upwelled asthenosphere forces the margin to subside in addition to the overloads from sea water and sediments. Therefore, the total subsidence in stretched basins includes faultcontroll...

Triangulated irregular networks (TIN) in landscape evolution models have the advantage of representing geologic processes that involve a horizontal component, such as faulting and river meandering, due to their adaptive remeshing capability of moving, adding and deleting nodes. However, the moving node feature is difficult to integrate with the accumulation of a three-dimensional (3D) subsurfac...

Magmatic and stratigraphic settings exert a first order control on the formation of various mineral deposit types. Some sating are rich in mineral wealth while others are barren. Stratigraphic setting is of particular importance where stratif&m or stratabound minerill deposits are concerned x orebodies are commonly restricted to specific stratigraphic intervals. For example. within the area bou...

Thick sequences of layered deposits are found in the Valles Marineris, Mars [I-31. They exhibit fine, nearly horizontal layering, and are present as isolated plateaus of what may once have been more extensive deposits. Individual sequences of layered deposits are as thick as 5 km. We have argued previously that the morphology of the deposits is most consistent with origin in standing bodies of ...

Introduction: The geology of Terby Crater (28S, 287W), located on the northern rim of Hellas impact basin on Mars, is documented through geomorphic and stratigraphic analyses using all currently released visible and thermal infrared image data and topographic information. This large (D=164km), Noachian-aged [1] crater has a suite of geomorphic units [2] and landforms including massive troughs a...

Recent onshore and offshore investigations in the Canarian archipelago, especially in the western islands of La Palma and El Hieno, have greatly improved the understanding of the genesis and evolution of these islands and allow interesting comparisons with other hotspot-induced oceanic island volcanoes, especially the Hawaiian archipelago. Genesis induced by hotspot activity and, consequently, ...

Atolls are faithful recorders helping us understand eustatic variations, the evolution of carbonate production through time, and changes in magmatic hotspots activity. Several early Cretaceous Mid-Pacific atolls were previously investigated ocean drilling, but due to low quality vintage seismic data available, few spatial constraints exist on their stratigraphic large-scale diagenesis. Here, we...

We present a geomorphologic map of Titan’s polar terrains. The map was generated from a combination of Cassini Synthetic Aperture Radar (SAR) and Imaging Science Subsystem imaging products, as well as altimetry, SARTopo and radargrammetry topographic datasets. In combining imagery with topographic data, our geomorphologic map reveals a stratigraphic sequence from which we infer process interact...
