Alternative models for the soils of Mars have invoked either the mineral nontronite (an iron-rich smectite clay) or the mineraliod palagonite (an oxidized, hydrated alteration product of basalt glass) as the major silicate component. Laboratory tests

Scanning electron microscopy and energy-dispersive X-ray spectrometry of untreated interior chips from three different specimens of the Chassigny meteorite confirm the presence of discrete grains of Ca-carbonate, Mg-carbonate, and Ca-sulfate. Morphol

The structure and chemical composition of the Lafayette meteorite were examined using several methods. The meteorite contains abundant hydrous post-magnetic alteration material consisting of ferroan smectite clays, magnetite, and ferrihydrite. The te

If the shergottite, nakhlite, and chassignite (SNC) meteorites' parent planet is Mars, then the aqueous precipitates found in them imply that oxidizing, water-based solutions may have been chemically active on that planet over the past 200-1300 milli

— Vacuum pyrolysis and quadrupole mass spectrometry were used to measure evolved-gas profiles and total concentrations of H2O, CO2, CO, SO2, S2, H2S, HCl, Cl, and hydrocarbons in both exterior and interior samples of shergottites (ALHA77005, EETA79

A petrographic survey of > 1600 chondrules in thin-sections of 12 different mildly to highly unequilibrated H-, L-, and LL-chondrites, as well as morphological and textural study of 141 whole chondrules separated from 11 of the same chondrites, was u
