Northwest Africa 10203 

Lunar (polymict breccia) Purchase Date: 2015 Morocco

Physical: Twenty-seven identically appearing pieces reportedly found together. Irregular exterior, no fusion crust, saw cut reveals a polymict breccia with numerous fragmental light and dark clasts. Petrography: (C. Agee, UNM) This polymict breccia has at least four distinct lithologies. 1) unbrecciated olivine gabbro with zoned clinopyroxene (~75%), acicular, plumose plagioclase (~15%), olivine (~5%), and minor titanomagnetite; 2) fragmental anorthositic gabbro breccia with ~75% plagioclase; 3) fragmental gabbroic breccia with approximately equal proportions of plagioclase, pyroxene and olivine; 4) shock melt veins and pools, some of which are vesicular. Accessory FeNi-metal, silica, ilmenite, troilite, chromite, and phosphate were observed in the fragmental breccias.

Geochem: (C. Agee and N. Muttik, UNM) Olivine gabbro: olivine Fa52.9.8±7.1, Fe/Mn=100±12, n=6; clinopyroxene Fs31.1±15.8Wo22.1±7.6, Fe/Mn=41±10, n=7; plagioclase An89.9±3.8Ab8.9±3.4Or1.1±0.8, n=3; anorthositic gabbro breccia: olivine Fa30.6±3.0, Fe/Mn=104±7, n=21; clinopyroxene Fs39.4±15.8Wo21.7±10.9, Fe/Mn=66±11, n=21; plagioclase An96.2±0.8Ab3.5±0.8Or0.2±0.1, n=6; gabbroic breccia: olivine Fa40.3±2.9, Fe/Mn=98±5, n=6; clinopyroxene Fs35.4±14.3Wo23.3±10.0, Fe/Mn=63±10, n=9; plagioclase An93.0±1.6Ab6.6±1.6Or0.4±0.1, n=4; Shock melt (10 µm defocused electron beam, proxy for bulk meteorite composition): SiO2=45.1±2.0, TiO2=0.54±0.38, Al2O3=24.3±6.2, Cr2O3=0.21±0.19, MgO=6.5±2.9, FeO=8.2±3.8, MnO=0.11±0.05, CaO=14.9±1.9, NiO=0.03±0.07, Na2O=0.49±0.13, K2O=0.10±0.03 (all wt%), n=40.

Shipping is usually sent via US Postal Service and I am happy to combine shipping for multiple purchases. I am happy to hold sending orders and combine future auctions into one shipment if desired as long as payment occurs at each auction close.

I recommend insurance as I will not be held responsible for uninsured lost or damaged parcels. Cost of U.S. delivery insurance is 2% of the total or $2.00, whichever is more. Changes to the USPS International insurance policy now require a rather expensive upgrade to Express Mail before they will agree to insure. For those who wish to insure foreign delivery please message me and I’ll be happy to send you the price.
