Patchy black fusion crust that is shiny is some areas and rough in others covers about 10 of the exterior. Exposed surfaces are heavily pitted gray matrix with some areas weathered to a dark gray and orange rust concentrated near pits. Fresh interior is light gray matrix with small (<1 mm) black inclusions, larger (up to 2 mm) white and yellow inclusions and a few large (3-4 mm) dark grey-brown clasts. Some larger white clasts contain smaller dark gray-black inclusions of their own. |
These two sections consist of a comminuted matrix of mineral fragments up to 1 mm in size, with clasts including coarse ophitic and medium grained granoblastic textures. Clasts reach up to 5 mm in maximum dimension. Pyroxenes are Fs21-63Wo2-44 and feldspars are An86-89Or1. The meteorites are similar enough that one description suffices, and are both howardites. |
