NWA 10667, Basaltic Eucrite Breccia, Micromount


NWA 10667 was recovered from the Saharan Desert of Morocco in 2015. It was classified by Dr. Tony Irving at UWS. Analysis showed the meteorite to be a shocked basaltic eucrite. The visible texture of this eucrite esembles that of a lunar meteorite, but it is not. Visually, this is one of the more interesting eucrites to originate from Vesta. It is composed of a dark groundmass matrix with lighter-colored clasts. The total known weight of this meteorite is very small (only 94 grams before classification) and there is not much available on the collector market.

Refer to the photo. The black centimeter cube is shown for scale and is not included. You are purchasing a single small fragment like the one shown. Your purchase will include a labeled gemjar for safe storage.
