Writeup from MB 88:
El Atchane 012 Algeria Found 2002 December 23 Enstatite chondrite (EL6) Two stones, totaling 331 g, were found by A. Goueslain and J. L. Parodi while searching for meteorites. The outer part is very oxidized, with neither metal nor sulfide left, but the interior is little altered. Classification and mineralogy (M. Bourot-Denise, MNHNP): rare chondrule relics, metal and sulfide are heterogeneously distributed, probably due to shock effects. Enstatite, Fs0.6 Wo1.7. Kamacite contains 0.9 wt% Si. Graphite rosettes and oldhamite needles are common in metal. The most abundant sulfides are troilite (1.4 wt% Cr, 0.6 wt% Ti), then alabandite; troilite contains abundant daubréelite in cleavages. Shocked, weathering grade W2. Specimens: type specimen 21.4 g, MNHNP; main mass with finders. | ||||||||||||||||||||||||
