Nakhlites experienced variable assimilation of &gt;2-billion-year-old altered high Re\/Os basaltic crust. This basaltic crust is distinct from the ancient crust represented by meteorites Allan Hills 84001 or impact-contaminated Northwest Africa 7034\/7533. Nakhlites and chassignites that did not experience crustal assimilation reveal that they were extracted from a depleted lithospheric mantle distinct from the deep plume source of depleted shergottites. The comagmatic origin for nakhlites and chassignites demonstrates a layered martian interior comprising ancient enriched basaltic crust derived from trace element\u2013rich shallow magma ocean cumulates, a variably metasomatized mantle lithosphere, and a trace element\u2013depleted deep mantle sampled by plume magmatism.&#8221;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>James M.
