Mafic Granulitic Impactite Northwest Africa 3163: a Unique Meteorite from the Deep Lunar Crust
نویسندگان
چکیده
Petrology and Mineral Compositions: The fresh, pale gray interior of this specimen has multiple shock fractures (with very minor calcite coatings) and some thin glass veinlets (Figure 2). This rock is a poikiloblastic recrystallized breccia, with larger grains of plagioclase (~70%) enclosing much smaller grains (less than 100 microns across) of pyroxene (~20%), olivine (~10%) and accessory Ti-chromite

Introduction: The discovery of spinel rich rock on the Earth’s Moon, detected by the M near-IR mapping spectrometer on the Chandrayaan-1 spacecraft [1] is among the most intriguing discoveries in a time filled with lunar revelations (e.g., [2]). The M spectrometer discerned several areas on the rim of the far-side Moscoviense basin which had near-IR reflectance spectra characteristic of abundan...
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 کاملPetrography and Geochemistry of Dhofar 733 – an Unusually Sodic, Feldspathic Lunar
Introduction: Dhofar 733 is a 98-g lunar meteorite collected in the Dhofar region of Oman in 2002 [1]. In the initial description [1], Dhofar 733 is described as an anorthositic granulitic breccia, one that is probably not paired with any other lunar meteorite on the basis of its unique texture and isolation from other lunar meteorites (the next closest lunar meteorite was found 22 km away). Th...
متن کاملEvidence for a widespread basaltic breccia component in the martian low-albedo regions from the reflectance spectrum of Northwest Africa 7034
Northwest Africa (NWA) 7034 is the first breccia meteorite from Mars, and unlike the shergottite, nakhlite, and chassignite (SNC) martian meteorites, it matches the estimated chemical composition of martian crust. Here we show that the visible-infrared reflectance spectrum of NWA 7034 is unique compared to other SNCs and is more similar than them to remotely sensed data from Mars, suggesting th...
متن کاملConnecting Lunar Meteorite Dhofar 961 to the South Pole Aitken Basin through Lunar Prospector Gamma-ray Data
Introduction: Lunar meteorite Dhofar 961, a complex, lithic-clast-rich impact breccia [1,2], was called out by [3-6] as a candidate for an origin in the South Pole – Aitken (SPA) Basin region of the Moon (the SPA Terrane) on the basis of its relatively mafic, but nonmare lithologic and major-element chemical composition. It also has an incompatible-element signature that differs from the KREEP-...
