Abstract
The geochemical composition of the sediments of Gale crater can be modeled using two component mixing between a weathered basalt and a sulfate rich endmember. This suggests that the amount of in-situ weathering occurring after deposition was minimal, and most of the variation in weathering indi-ces can be explained simply through addition of Ca-sulfate minerals during diagenesis. Evidence for burial of Gale sediments can be explained through the pres-ence of large ice/dust deposits.
