Writeup from MB 104:

Northwest Africa 10093 (NWA 10093)

Algeria

Purchased: Jul 2013

Classification: Ordinary chondrite (LL5)

Physical characteristics: The oblong, round stone is entirely fusion-crusted and desert-varnished.

Petrography: (A.E. Rubin, UCLA) Chondrules are recrystallized, but readily delineated, consistent with type 5. Plagioclase grains generally 15 μm or smaller, suggesting a petrographic grade lower than 6. No polysynthetically twinned low-Ca clinopyroxene, indicating not type 3-4. Average chondrule diameter is ~600 μm, characteristic of LL.
