Rare-Earth Minerals in Martian Meteorite NWA 7034/7533: Evidence for Fluid-Rock Interaction in the Martian Crust

Abstract

Monazite, chevkinite-perrierite and xenotime are common rare-earth minerals in terrestrial rocks and important repositories for the rare-earth-elements (REE). Liu and Ma [1-2] reported finding monazite, chevkinite-perrierite and xenotime in NWA 7034/7533, the 'Black Beauty' meteorite. Here, we provide a more detailed textural and compositional analysis of these minerals; our results suggest an origin via fluid-rock interaction.
