Macroscopic Description: Kathleen McBride
The exteriors of these carbonaceous chondrites have patches of rough, black fusion crust with polygonal fractures. The interior is a dark gray matrix.

Thin Section (, 3) Descriptions: Gretchen Benedix, Linda Welzenbach, and Tim McCoy

QUE 99675 Plane-Pol. Light QUE 99675 Cross-Pol. Light
These sections are so similar that a single description suffices. The section consists of large (up to 1 mm) chondrules in a matrix of finer-grained silicates, sulfides, and very abundant magnetite. The meteorites are little weathered, but extensively shock blackened. Silicates are homogeneous. Olivine is Fa28 and orthopyroxene is Fs24-25. The meteorites are CK4 chondrites.
