This talk will focus on the\norigins of geochemical diversity an d estimates of oxygen\nfugacity among igneous and least altered sedimentar y rocks\nmeasured by rover missions. Relative influences of partial\nmelti ng\, fractional crystallization\, and mantle metasomatism\nwill be explore d. Terrestrial mantle xenoliths from alkaline\nprovinces are considered as analogues to the Martian\nmantle\, including cumulate xenoliths from post -shield\nHawaiian volcanoes and metasomatized xenoliths from\nMount Taylor Volcanic Field (New Mexico). Such a\ncomparison is worthwhile because the Martian upper\nmantle is likely a mixture of primary\, residual\,\nmetaso matized\, and cumulate mantle.
