The Windjana drill sample, a sandstone of the Dillinger member (Kimberley formation, Gale Crater, Mars), was analyzed by CheMin X-ray diffraction (XRD) in the MSL Curiosity rover. From Rietveld refinements of its XRD pattern, Windjana contains the following: sanidine (21% weight, ~Or 95); augite (20%); magnetite (12%); pigeonite; olivine; plagioclase;(More)
Introduction: Kaersutite is a Ti-rich amphibole defined as having between 0.50 and 0.80 Ti atoms per formula unit [1, 2]. It is commonly found in terrestrial mantle-derived peridotites, in alkalic rocks with obvious high-pressure histories [3, 4], and in some SNC meteorites for which the exact petrogenetic histories are unknown [5, 6]. Because kaersutite is(More)

The Mars Exploration Rover Spirit investigated the igneous and alteration mineralogy and chemistry of Home Plate and its surrounding deposits. Here, we focus on using thermochemical modeling to understand the secondary alteration mineralogy at the Home Plate outcrop and surrounding Columbia Hills region in Gusev crater. At high temperatures (300 °C),(More)
