Abstract

The objective of this study is to document the secondary mineral assemblages in two occurrences of terrestrial iddingsite and compare these with the iddingsite in the ALHA 77005 martian meteorite: a lherzolitic shergottite). Short laser Raman spectroscopic traverses: hundreds of μm long) across olivine alteration fronts provide information about changes in the mineral assemblage with alteration. Data from the Raman traverses are combined with data from electron microprobe traverses at the same locations to provide information regarding element mobility near the zones of alteration and to confirm mineral identifications made by Raman spectroscopy. This information is used along with petrographic observations to constrain the conditions of alteration on Mars and deliberate on the environments and modes of alteration.
