A Laboratory Simulation Experiment of Hydrothermal Processes on Mars
Hydrothermal processes on Mars: It has been suggested that hydrothermal process may have been active in the history of Mars[1]. This concept is supported by three lines of evidences: (1) widespread evidences of volcanic activity on Mars; (2) high levels of WEH (water-equivalent-hydrogen) found in two large equatorial regions on Mars (ODY_NS) [2]; (3) The ground ice excavated by meteorite impact...
متن کاملLaboratory Hydrothermal Alteration of Basaltic Tephra by Acid Sulfate Solutions: an Analog Process for Martian Weathering
Introduction: Sulfur is a major chemical component of the Martian surface materials and is thought to have a volcanic origin. Pathfinder and Viking chemical analyses revealed SO3 compositions of “soils” and dust from about 4 to over 7 wt. % [1,2]. Although we know that S is chemically important, we do not know its speciation. Small amounts of sulfates (e.g., Ca and Mg sulfates) and sulfides (e....
متن کاملLaboratory simulations of acid-sulfate weathering under volcanic hydrothermal conditions: Implications for early Mars
We have completed laboratory experiments and thermochemical equilibrium models to investigate secondary mineral formation under conditions akin to volcanic, hydrothermal acid-sulfate weathering systems. Our research used the basaltic mineralogy at Cerro Negro Volcano, Nicaragua, characterized by plagioclase, pyroxene, olivine, and volcanic glass. These individual minerals and whole-rock field s...
متن کاملHydrothermal alteration and diagenesis of terrestrial lacustrine pillow basalts: Coordination of hyperspectral imaging with laboratory measurements
We investigate an outcrop of 187 Ma lacustrine pillow basalts of the Talcott Formation exposed in Meriden, Connecticut, USA, focusing on coordinated analyses of one pillow lava to characterize the aqueous history of these basalts in the Hartford Basin. This work uses a suite of multidisciplinary measurements, including hyperspectral imaging, other spectroscopic techniques, and chemical and mine...
متن کاملEditorial: Hydrothermal microbial ecosystems
The papers in the " Hydrothermal Vent " research topic cover a range of microbiological research in deep and shallow hydrothermal environments, from high temperature " black smokers, " to diffuse flow habitats and episodically discharging subsurface fluids, to the hydrothermal plumes. Together they provide a snapshot of current research interests in a field that has evolved rapidly since the di...
