Introduction: Each of the three Tharsis Montes volcanoes on Mars has unusual fan-shaped deposits located exclusively to the northwest of each shield. The fan-shaped deposits of the Tharsis Montes generally share three major facies: 1) Ridged facies, 2) Knobby facies, and 3) Smooth facies. Here we examine the Pavonis fan-shaped deposits using new Mars Global Surveyor and Mars Odyssey data. Any e...

Abstract We analyze the evolution of undeformed Middle to Late Pleistocene deposits Es Codolar (Southern Eivissa, Western Mediterranean). The outcrop records a succession characterized by alternation aeolian, colluvial and alluvial fan palaeosols that result in complex stratigraphic architecture. In this area, aeolian beds, are exposed along sea-cliffs for almost 500 m, allowing detailed descri...

. The earthquakes of 1894, 1944, 1952 and 1977 occurred in the province San Juan central-wesern Argentina caused numerous processes soils sediment liquefaction, including those Ullum-Zonda valley. Historical records showed cracks, sand volcanoes, craters differential settlements, which significant damage to housing agro-industrial sector region. In this work, we carried out a study susceptibili...

This study provides a detailed sedimentological, stratigraphic and depositional model for the lower Whakataki Formation. The fine-grained nature of turbidite successions common Tbcde suggests deposition associated with medial to distal submarine fan deposits. However, textural compositional immaturity, combined high carbonaceous carbonate content clastic sediments indicates proximal detrital in...

Fan-shaped sedimentary landforms on Mars are important geomorphic markers of past water flow and characterizing the distribution morphology these features can yield insights into planet's climatic evolution. We present a new database 1501 martian fan-shaped that builds upon previous surveys uses Context Camera images. This comprehensive global survey includes both alluvial fans putative deltas,...

This volume presents a series of papers on the geomorphology, sedimentology and dynamics of alluvial fans, selected from those presented at the 'Alluvial Fans' Conference held in Sorbas, SE Spain in June 2003. The conference was sponsored primarily by the British Geomorphological Research Group and the British Sedimentological Research Group, both organizations affiliated to the Geological Soci...

the kashkan formation (paleocene to middle eocene), consists of conglomerate, sandstone, and siltstone in the zagros folded zone, southwest iran. type of the sedimentary facies, architectural elements and trace fossils show that kashkan deposits were formed in a low sinuosity braided stream system, with north to south flow direction. the formation displays coarsening-upward succession reflects ...

Introduction: The Hypanis fan-shaped deposit in Xanthe Terra has been interpreted by many to be a late Noachian aged delta along the dichotomy boundary [15]. The putative delta was a compelling candidate landing site for the future Mars 2020 and ExoMars rover missions as it was positioned at the edge of an open basin, could have been an ideal environment for biosignature formation, concentratio...
