NWA 11216 (Lunar Feldspathic Breccia)

Multiple stones totaling 222.34g were purchased out of Morocco in February of 2017. A sample was sent to Dr. Anthony Irving for classification and determined to be a Lunar Feldspathic Breccia. Stones feature many clasts set within a black and grey matrix. Multiple areas of shock/impact melt exist along with a rather large amount of metal blebs and small vesicles spread throughout the matrix, thus indicating it is likely a regolith breccia caused by an impactor!  I prepared several slices from one of the bigger stones and will be cutting many smaller stones soon. Slices feature one polighed side and will come in a padded meteorite display box. If you are interested in a small whole stone or an endcut/split individual please send me a message! Otherwise, more material will be added shortly.

Petrography as follows:

Breccia composed of angular mineral grains of anorthite, olivine, pigeonite, subcalcic ferroaugite, Ti-free chromite, Ti-Cr-Fe spinel, ilmenite (with rare inclusions of baddeleyite) and fayalite in a finer grained, vesicular matrix containing kamacite, troilite and minor celestite. Olivine (Fa17.5-27.9, FeO/MnO = 94-118, N = 3), orthopyroxene (Fs22.6Wo4.0, FeO/MnO = 72), pigeonite (Fs24.4Wo8.1; Fs33.3Wo16.4; FeO/MnO = 62-73; N = 2), subcalcic ferroaugite (Fs73.5Wo25.6, FeO/MnO = 66), plagioclase (An94.8-96.8Or0.4, N = 2).
