IMCA # 3948, IMCA # 5051 INTERNATIONAL METEORITE COLLECTORS ASSOCIATION Authenticity GUARANTEED HELLO ALL OLD AND NEW GUESTS!!! We are a team of meteorite and fossil hunters.We search worldwide for new and known meteorites. Since 1995, we have mounted expeditions to Tsarev, Brahin, Kunya Urgench, Dronino, Markovka, Seymchan, Sikhote-Alin and many others in Russia and nearby. We have also collected many meteorites from North Africa, the Middle East, Europe an...d the United States.We have gathered samples of almost all types of known meteorites, including a large collection of lunar meteorites.We are on the world market since 2000, and on eBay since 2004. We ship worldwide from USA. We easy combine shipping. We accept different ways of payments, but PayPal is very preferred. As always we hope the best is in future. We'll make a very good business with all you our friends and partners. Please do not hesitate ask us any questions. Happy bidding! Cometshop teamNorthwest Africa 6355 (NWA 6355)Morocco
Found: June 2009
Classification: Lunar meteorite (feldspathic breccia)
History: Found in southern Morocco in June 2009 and purchased by a consortium led by Matt Morgan from a Moroccan dealer in September 2010.
Physical characteristics: A single fine-grained, brittle stone (760 g) with no obvious fusion crust. The interior is dark gray and resembles devitrified glass with dispersed small white clasts.
Petrography: Clast-laden vitric breccia consisting of fine-grained mineral debris (mostly pyroxenes, olivine and anorthite) and sparse polycrystalline igneous clasts in a heterogeneous, "swirly" glassy matrix (in part vesicular). Mineral clasts include anorthitic plagioclase, low-Ca pyroxene, pigeonite, olivine, Mg-bearing ilmenite, kamacitic metal and troilite. Lithic clasts include microgabbronorite (composed of subcalcic augite, orthopyroxene, anorthite, Mg-bearing merrillite, silica polymorph, ilmenite, troilite and baddeleyite).
Geochemistry: Low-Ca pyroxene (Fs37.5-61.2Wo2.4-5.2, FeO/MnO = 65-88), pigeonite (Fs23.5-45.5Wo10.3-11.1, FeO/MnO = 48-76), subcalcic augite (Fs13.0Wo37.0, Fs17.6Wo30.1, Fs25.7Wo35.0, FeO/MnO = 55-59), augite (Fs11.3Wo41.8; FeO/MnO = 49), olivine (Fa29.5-33.9, FeO/MnO = 81-104), plagioclase (An91.6-96.1Or0.5-0.1). Bulk composition (R. Korotev, WUSL): FeO 5.8 wt%, La 13.0 ppm, Sm 6.1 ppm, Yb 3.95 ppm, Th 1.87 ppm.
Classification: Achondrite (lunar, feldspathic breccia). This stone is almost identical in texture, mineral compositions and bulk composition to NWA 4936, NWA 5406 and NWA 6221. It is possibly paired with those stones and is reportedly from the same find location.
We are offering a thin slice cut from the stone. The weight is 0.59 grams. The slice is coming in a nice box as shown on the last image.
SHIPPING:1. Within USA will be $9.2. Out of USA will be $15.
GOOD LUCK.
