NWA 2085This meteorite is the best looking Impact-melt breccia on the market. Even Bob Haag thinks it looks as good as Cat Mountain. I bought this meteorite and have all of it. I have donated a complete slice to the University of Arizona for further study, and they will be publishing a complete paper regarding this stunning find. This is a chance to get a one of a kind meteorite. It is suitable for even the top museum collections in the world. Below is the exact data as submitted to the Meteoritical Society: Northwest Africa 2085 A 2.7 kg single stone was purchased in Rissani, Morocco in October 2003. Description and classification (T. Bunch and J. Wittke, NAU): exceptional melt rock: centimeters-size L chondrite clasts are surrounded by crystallized melt. The melt contains oblate to round, eutectic-textured, masses (up to 2.5mm) of taenite metal set in troilite. The metal/troilite complexes have weak flow alignment in a matrix of tabular to equant olivines (< 0.8 mm), which have no apparent preferred orientation, and SiO2-rich glass, in addition to small, recrystallized chondrite fragments. Melt olivine, Fa22.8 (22.1 ö 23.8); taenite, Ni = 15.4 wt %, range, 13.6 ö 16.1%; troilite, Ni = 0.42 wt %; glass, SiO2 = 74.6 wt %, FeO = 3.6 %. Clast chondrules and matrix are partially recrystallized from shock effects; olivine, Fa22.2 ö 23.9 ; opx Fs18 ö 19.9 Wo1.4-2.0. Shock level, S4 ö S6; weathering grade, W1/2. Specimens: 88.5 g, NAU; main mass, Farmer. Please note, this meteorite is very difficult to properly photograph, the pieces look even better in person. |
