Exterior of this meteorite is mottled red-brown and dark brown-black with iridescent oxidation spots and extensive fracturing. There are a few spots of possible fusion crust that are rough and black. Fresh interior is very crumbly gray-brown matrix with reflective mineral inclusions and extensive red-orange weathering throughout. |
The section consists of mineral fragments of pyroxene, feldspar and SiO2 grains in a matrix with abundant metal and sulfide. Metal occurs as stringers that reach 2 mm in maximum dimension and also as blebs. One area of the section is notably rich in sulfide and poor in FeNi metal. Pyroxene compositions are Fs37Wo3 and Fs27Wo42. Feldspars are An90-94Or0.2. Fe/Mn is ~29. The meteorite is likely a clast from a mesosiderite. Pairing with MIL 13174 should be considered. |
