The martian sulfur cycle includes sulfur output from the deep interior to the surface and atmosphere through magmatism and volcanism as well as assimilation of sulfur-bearing phases from the surface or shallow subsurface into rising magmas (Farquhar et
Isotopic links between atmospheric chemistry and the deep sulphur cycle ...
2014年4月16日 · The presence of igneous sulphides in Martian meteorites with sulphur isotope signatures indicative of mass-independent fractionation suggests the assimilation of sulphur both during passage of ...
Sulfur on Mars | Elements | GeoScienceWorld
2010年4月1日 · The sulfur cycle is arguably the most important geochemical cycle on Mars because the transfer of sulfur places limits on Mars's differentiation processes, sedimentary, geomorphic and aqueous processes, past climate, and current and past habitability.
Geochemical Reservoirs and Timing of Sulfur Cycling on Mars
2012年11月30日 · While the Earth’s surface chemistry and climate are intimately tied to the carbon cycle, it is the sulfur cycle that most strongly influences the Martian geosystems. The presence of sulfate minerals observed from orbit and in-situ via surface exploration within sedimentary rocks and unconsolidated regolith traces a history of post-Noachian ...

Sulfur concentration of martian basalts at sulfide saturation at …
2014年4月15日 · Sulfur cycle for Mars is of particular interest because sulfur is thought to be ubiquitous in various martian reservoirs such as the atmosphere, crust, mantle, and core as revealed by data from remote sensing, from Odyssey spacecraft, Viking missions, pathfinder mission and Mars Exploration Rover mission (Clark et al., 1976, Clark and Baird ...
Sulfur Cycling and Mass Balance at Meridiani, Mars
2019年10月25日 · Sedimentary rocks highly enriched in sulfur were investigated by the Opportunity rover at Meridiani Planum, Mars. These materials extend over a broad region. Mass balance calculations were completed to assess whether or not the proposed scenarios for Meridiani sulfur and sediments could be reconciled with observations.
A Sulfur Dioxide Climate Feedback on Early Mars | Science - AAAS
2007年12月21日 · In this paper, we explore the implications of an active sulfur cycle, linked to the carbon cycle, on the climate and surface chemistry of early Mars. In an early martian sulfur cycle, volcanic outgassing of sulfur to the atmosphere and surface environment, primarily as SO 2 and H 2 S, would be balanced by photochemical sinks and precipitation ...
Sulfur and the Sulfur Cycle on Mars - ResearchGate
2009年3月1日 · The Mars Exploration Rover (MER), Opportunity, showed that layered sulfate deposits in Meridiani Planum formed during a period of rising acidic ground water.
