Petrogenesis of lunar meteorite EET 96008
Lunar meteorite EET 96008 is a fragmental breccia that predominantly consists of basaltic mineral clasts (0.5–2 mm), along with minor lithic fragments and breccia clasts. The matrix consists mainly of smaller mineral fragments ( 0.5 mm), bound by glassy cement, the majority of which are pyroxene and plagioclase. The pyroxene possesses extensive exsolution lamellae. These lamellae, up to 1 m in ...
متن کاملApatite as a Key to Evaluating the Volatile Budget of Martian Magmas: Implications from the Chassigny Meteorite
Introduction: Apatite has been extensively studied on Earth because of its geological, geobiological, and materials importance [1], and it is one of the most common mineralogical reservoirs for phosphorus on Earth. Apatite is also present in each of the three types of SNC meteorites, implying the same may also be true for Mars. In addition to phosphorus, apatite commonly contains some combinati...
متن کاملCarbonates in the Martian meteorite
Despite evidence for liquid water at the surface of Mars during the Noachian epoch, the temperature of early aqueous environments has been impossible to establish, raising questions of whether the surface of Mars was ever warmer than today. We address this problem by determining the precipitation temperature of secondary carbonate minerals preserved in the oldest known sample of Mars’ crust—the...
متن کاملAmino acids in the Martian meteorite Nakhla.
A suite of protein and nonprotein amino acids were detected with high-performance liquid chromatography in the water- and acid-soluble components of an interior fragment of the Martian meteorite Nakhla, which fell in Egypt in 1911. Aspartic and glutamic acids, glycine, alanine, beta-alanine, and gamma-amino-n-butyric acid (gamma-ABA) were the most abundant amino acids detected and were found pr...
متن کاملConstraints on the composition and petrogenesis of the Martian crust
[1] Spectral interpretation that silicic rocks are widespread on Mars implies that Earth’s differentiated crust is not unique. Evaluation of observations bearing on the composition of the Martian crust (Martian meteorite petrology and a possible crustal assimilant, analysis of Mars Pathfinder rocks, composition of Martian fines, interpretation of spacecraft thermal emission spectra, and inferre...
