102.4 gram end cut.   CR-an

TKW 115 kg. Fall not observed. Found 14 February 2011, in the Tenere desert, Niger.

From the MetBul:
The dominant lithology has a coarse grain size. It consists of olivine (poikilitically enclosed within pyroxenes in the relic chondrules), a small amount of plagioclase, 10% metal in rounded or oval-shaped grains often edged by chromite, and minor sulphides in small grains. The interchondrule matrix consists of subhedral crystals of olivine embedded in plagioclase and within anhedral crystals of chromite and phosphate that are up to 1 mm in size. Two distinct plagioclase compositions are present: An46.4Or2.2 in the matrix and An26.6Or5.2 in chondrule relics. A second lithology is finer grained and porous, without large metal grains but with fairly abundant sulphide grains.

Fractured edges are as or more interesting than a cut and polished face, etc. I am lucky to have several specimens including a broken fragment with crust on it that really is different to see that the average meteorite. The texture and look of Tafassasset is one of a kind to me.
