DESCRIPTION:The Mars Mantle: Insights from Rover Missions and Terrestrial A
 nalogues\n\nBasaltic igneous rocks represent samples of a planet’s\ninteri
 or and give insight to the degree of heterogeneity or\nhomogeneity of the 
 interior. 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.
