Global mineralogical and aqueous mars history derived from OMEGA/Mars Express data.
Global mineralogical mapping of Mars by the Observatoire pour la Mineralogie, l'Eau, les Glaces et l'Activité (OMEGA) instrument on the European Space Agency's Mars Express spacecraft provides new information on Mars' geological and climatic history. Phyllosilicates formed by aqueous alteration very early in the planet's history (the "phyllocian" era) are found in the oldest terrains; sulfates ...
متن کاملthe role of russia in transmission of energy from central asia and caucuses to european union
پس ازفروپاشی شوروی،رشد منابع نفت و گاز، آسیای میانه و قفقاز را در یک بازی ژئوپلتیکی انرژی قرار داده است. با در نظر گرفتن این منابع هیدروکربنی، این منطقه به یک میدانجنگ و رقابت تجاری برای بازی های ژئوپلتیکی قدرت های بزرگ جهانی تبدیل شده است. روسیه منطقه را به عنوان حیات خلوت خود تلقی نموده و علاقمند به حفظ حضورش می باشد تا همانند گذشته گاز طبیعی را به وسیله خط لوله مرکزی دریافت و به عنوان یک واس...
15 صفحه اولComparison of Effusive Volcanism at Olympus, Arsia, Pavonis, and Ascraeus Montes, Mars from Lava Flow Mapping Using Mars Express Hrsc
Introduction: The High Resolution Stereo Camera (HRSC) onboard ESA's Mars Express (MEX) orbiter [1] has provided 12.5 m/pixel projected images for a north-south transect of the four major Tharsis shield volcanoes. These data provide an unprecedented opportunity to examine lava flows at high resolution with regional context. Our objective is to characterize late-stage effusive processes and iden...
متن کاملGeochemical and mineralogical indicators for aqueous processes in the Columbia Hills of Gusev crater, Mars
[1] Water played a major role in the formation and alteration of rocks and soils in the Columbia Hills. The extent of alteration ranges from moderate to extensive. Five distinct rock compositional classes were identified; the order for degree of alteration is Watchtower ffi Clovis > Wishstone ffi Peace > Backstay. The rover’s wheels uncovered one unusual soil (Paso Robles) that is the most S-ri...
متن کاملSulfates in Valles Marineris and Implications for Mars' Aqueous History
Introduction: Mapping the type and distribution of hydrated mineralogy is one way to track the aqueous history of Mars. Sulfates are a potentially good tracer of past climate because they form by aqueous processes , so their presence, volume, and process of formation can characterize how much water was available. The sulfates in Valles Marineris (monohydrated Mg or Fe sulfate and polyhydrated s...
