Characterization of the Weathering Products of Antarctic Martian Meteorite Analog Materials and Implications for the Formation of Martian Surface Fines
Layered and massive outcrops on Mars, some as thick as 4 km, display the geomorphic attributes and stratigraphic relations of sedimentary rock. Sequences in some locations imply a dynamic depositional environment during early martian history. Subaerial (such as aeolian, impact, and volcani-clastic) and subaqueous processes may have contributed to the formation of the layers. Affinity for impact...
متن کاملA model for formation of dust, soil, and rock coatings on Mars: Physical and chemical processes on the Martian surface
[1] A model is presented here to explain the generation of surface material on Mars using chemical, magnetic, and spectroscopic data from Mars and geologic analogs from terrestrial sites. One basic premise is that the dust/soil units are not derived exclusively from local rocks, but are rather a product of global, and possibly remote, weathering processes. Another assumption in this model is th...
متن کاملDraft Genome Sequence of Rhizobium sp. H41, a Rock-Weathering Bacterium from a Weathered Rock Surface
Rhizobium sp. H41 isolated from weathered tuff can weather tuff and release Fe, Si, and Al from the rock under nutrient-poor conditions. Here, we report the draft genome sequence of strain H41, which may facilitate a better understanding of the molecular mechanism involved in rock weathering by the bacterium.
متن کاملThe effect of surface rock fragments deployment pattern on soil erosion processes under simulated conditions
Extended abstract 1- Introduction The Soil surface characteristics have significant effects on the erosion process. The wide areas of watershed soil surfaces are covered with considerable amounts of rocks and pebbles. Surface rock fragments, resulting in water connectivity, change during the erosion process. Rock fragments on the soil surface may increase the infiltration and reduce soil loss...
متن کاملAcidic Weathering of Martian-relevant Phyllosilicates
Introduction: The OMEGA reflectance spectrometer onboard Mars Express [1, 2] and CRISM onboard the Mars Reconnaissance Orbiter [3, 4] have identified large phyllosilicate deposits on heavily impacted Noachian aged terrains, some associated with fluvial and deltaic deposits [3, 4]. This contrasts with the sulfate deposits which are mainly present in Hesperian aged terrains [2, 5, 6]. This differ...
