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...
متن کاملLunar Meteorite Dhofar 026: a Shocked Granulitic Breccia, Not an Impact Melt
Introduction: Lunar meteorite Dhofar 026 was previously interpreted as an impact melt [1, 2]. Detailed studies of the rock and comparison to Apollo lunar samples 15418 and 60017 indicate that the rock instead is a shocked, partly melted, granulitic breccia. These studies, presented by [3], are summarized herein. Petrology of Dhofar 026: Most of the rock consists of blocky patches of monomineral...
متن کاملLunar Meteorite Dhofar 026: a Second-generation Impact Melt
Introduction: The meteorite Dhofar 026 (Dh26) was found in Oman in January, 2000 [1]. It is a clastpoor, anorthositic, crystalline melt breccia with no fusion crust and little terrestrial weathering. Solar wind abundance measurements show that it is unpaired with the lunar regolith breccia Dhofar 025 [2]. The Dh26 oxygen isotopic composition indicates its lunar origin [3], while its majorand tr...
متن کاملPetrography and Chemistry of Impact-melt Clasts in Apollo
Introduction: The preponderance of 3.9 Ga lunar impact-melt rock ages and the dearth of older samples of unequivocal impact origin, from either the Apollo collection or lunar meteorites, suggest an extraordinary bombardment event in the Earth-Moon system at ~3.9 Ga. We have begun to study another set of samples, impact melts and crystalline lunar spherules (CLS) within demonstrably old Apollo b...
