Geochemistry and mineralogy of a feldspathic lunar meteorite (regolith breccia), Northwest Africa 2200

Petrography and Mineralogy of Dhofar 1428 Lunar Highland Regolith Breccia

Introduction: Dhofar 1428 is a lunar feldspathic breccia found in 2006. Bunch et al. [1] briefly described mineral chemistry of Dhofar 1428. Korotev and Zeigler [2] analyzed its bulk FeO and Sm compositions. Here, we report such detailed data for Dhofar 1428. Results and Discussion: Dhofar 1428 has a distinct breccia texture with numerous fragments of rock, mineral, and glass all welded by a gl...

Mineralogy and petrology of a lunar highland breccia

Mapping the Spatial Distribution, Mineralogy, and Geochemistry of Lunar Highlands

Introduction: Knowledge of the surface mineralogy and chemistry of the crust is central to understanding the evolution of the lunar crust. Using the 5-band ultravioletvisible (UVVIS) Clementine data set, Tompkins and Pieters [1] showed that approximate mineralogy could be determined from Clementine data and analyzed 109 impact craters detailing the approximate mineralogy, or rocktypes, of their...

Unique meteorite from early Amazonian Mars: water-rich basaltic breccia Northwest Africa 7034.

We report data on the martian meteorite Northwest Africa (NWA) 7034, which shares some petrologic and geochemical characteristics with known martian meteorites of the SNC (i.e., shergottite, nakhlite, and chassignite) group, but also has some unique characteristics that would exclude it from that group. NWA 7034 is a geochemically enriched crustal rock compositionally similar to basalts and ave...
