Algeria

Find: 2019

Classification: Ordinary chondrite (LL3)

History: Purchased in 2019 by Matthew Stream from Mostafa Hnini in Algeria.

Physical characteristics: Single stone with dark-brown fusion crust.

Petrography: (D. Sheikh, Cascadia) This sample contains chondrules (720±100 µm, n=20) set in a fine-grained, slightly opaque matrix with accesory Fe-Ni metal and troilite.

Geochemistry: Olivine (Fa19.3±11.0 ,range Fa0.5-44.2, n=43), Low-Ca Pyroxene (Fs14.7±9.5Wo1.4±0.6, range Fs1.0-27.9Wo0.4-2.9, n=19).

Classification: Ordinary chondrite (LL3) based on range in Fa and Fs values, and on average chondrule diameter.
