Rabt Sbayta 008


Rio de Oro, Western Sahara

Find: 2016 November

Mass: 229 g


Lunar Meteorite (feldspathic breccia)


History: Purportedly found at a location NE of Bir Anzarane and purchased by Ben Hoefnagels in January 2017 from a dealer in Ouarzazate, Morocco.


Physical characteristics: A single broken, pale beige-colored, roughly prismatic-shaped stone (229 g) with degraded fusion crust coating three sides.


Petrography: (A. Irving and S. Kuehner, UWS) Leucocratic, clast-rich breccia composed predominantly of anorthite, olivine, pigeonite and subcalcic augite with accessory ilmenite, chromite, troilite and kamacite.


Geochemistry: Olivine (Fa24.4-60.5, FeO/MnO = 84-89, N = 3), orthopyroxene (Fs20.6Wo3.2, FeO/MnO = 51), pigeonite (Fs21.29Wo7.7, FeO/MnO = 46), subcalcic augite (Fs21.0Wo23.6; Fs29.5Wo32.1; FeO/MnO = 41-54), plagioclase (An95.6-96.3Or0.2, N = 2).


Classification: Lunar (feldspathic breccia). Although this lunar specimen was found in the same dense collection area as the Rabt Sbayta 002, Rabt Sbayta 004, Rabt Sbayta 005 and Rabt Sbayta 006 stones (but at a different location from Gataa Sfar), it differs from those stones in both petrologic and bulk compositional characteristics and thus is not paired with them (nor with Rabt Sbayta 007).


Specimens: 24.3 g including a polished slice at UWB; remainder with Mr. B. Hoefnagels.


Randy Says…

This is a new one, somewhat like the NWA 3163 pairs in composition but a different texture.
