Black Butte 001 (BB 001) 41°24.061’N, 118°13.198’W Nevada, United States Find: 2015 Aug 8 Classification: Ordinary chondrite (H3-4) History: While searching for meteorites on a small drylake, Robert Verish recovered this stone on a west-facing stranding-surface. Physical characteristics: This 27.5 g stone is an oriented individual with the aft-end having a subtle overlipping. Originally, this stone had a discoidal shape, but a fragment is missing, and now it is shield-shaped with a smooth, brownish-black fusion-crusted exterior. Cut surface shows a mottled, light-brown interior. Petrography: (D. Sheikh, FSU) Sample contains well-defined chondrules (Av. 550 μm) along with metal and troilite. Both unequilibrated and equilibrated clasts present. Geochemistry: Olivine in type 3 clasts (Fa15.2-26.3, n=10), Olivine in type 4 clasts (Fa18.6±0.6, n=12), Low-Ca Pyroxene in type 4 clasts (Fs17.0±0.7Wo1.3±0.2, n=10). Classification: Ordinary Chondrite (H3-4). The sample contains both unequilibrated (type 3) and equilibrated (type 4) clasts. Specimens: 5.5 grams at UCLA; main mass with Verish. | ||||||||||||||||||||||||||||||||
