Macroscopic Description: Robbie Marlow Dull, black fusion crust covers 40% of the exterior of this carbonaceous chondrite. Numerous chondrules of assorted sizes can be seen protruding from the exterior surfaces. Cleaving DAV92300 revealed a medium-gray interior that is friable and fine-grained.
Thin Section (,3) Description: Brian Mason The section shows an aggregate of small (0.01-0.05 mm) olivine grains and minor opaque material, with a few chondrules up to 0.9 mm across. Olivine composition is Fa32; a little pyroxene, Fs26, and plagioclase, An50, were analyzed. The opaque material is largely magnetite. The meteorite is a C4 chondrite of the Karoonda subtype.
