57.9 gram full slice. 115 x 100 x 2 mm.   Achondrite-ung

TKW 22.86 kg. Fall not observed. Found May 2020, Adrar, Algeria.

From the MetBul:

The stones under classification (combined weight 31.783 kg) lack fusion crust, and have an overall relatively coarse grained, tan and beige appearance with sporadic larger green, yellow-green and less commonly yellow-brown crystals (up to 9 cm by 4 cm in some specimens).

   

Scott writes:

Erg Chech 002 is already well represented on MPOD (7 other entries), but some new material recently became available that is especially pretty and shows two distinct lithographies. In this material, there’s the "typical" Erg Chech 002 fine grain lithography, and a more gemmy and crystalline form seen in most of this slice. Perhaps these are due to two separate magma flows, with the crystalline one cooling more slowly to allow the longer crystals to form?
