Macroscopic Description - Kathleen McBride, Cecilia Satterwhite | |
Exterior surfaces are covered with smooth chocolate brown to black fusion crust. The interiors range from hard to soft black rusty matrix with dark and light colored chondrules/inclusions. | |
Thin Section Description (,2) - Tim McCoy | |
The sections are so similar that a single description suffices. The sections consist of abundant small (up to 1 mm) chondrules, chondrule fragments and mineral grains in a dark matrix. Metal and sulfide occur within and rimming the chondrules. Olivine ranges in composition from Fa0-55, with a continuous range of intermediate compositions and a slight peak at Fa1-5. Pyroxene is Fs1-2. The meteorites are CO3 chondrites. |
