Sheikh, Cascadia) Sample is a chondrite comprised of small chondrules (~ 50 vol. %, Av. diameter ~200 µm, primarily PO and POP textures), refractory inclusions (~100 µm, <1 vol. %) and isolated mineral fragments set within a fine-grained matrix (~50 vol. %). Accessory phases include Fe-Ni metal and troilite.

Geochemistry: Olivine (Fa26.5±17.5, range Fa0.3-50.0, n=40), Low-Ca Pyroxene (Fs2.1±0.4Wo1.3±0.8, range Fs1.5-2.9Wo0.8-3.4, n=8).
