Macroscopic Description - Kathleen McBride | |
The exterior has a dull black fractured fusion crust. The interior is a black matrix with evaporites and light colored chondrules. | |
Thin Section Description (,2) - Tim McCoy, Lauren LaCroix, Linda Welzenbach | |
The section consists of a few small chondrules (up to 1 mm), mineral grains and CAIs set in a black matrix; rare metal and sulfide grains are present. Chondrules are elongated as a result of flattening due to shock. Olivine compositions are Fa1-39, orthopyroxene is Fs1-5. The meteorite is a CM2 chondrite. |
