Sample No.: DAV92300

Location: David Glacier

Dimensions (cm): 4.0 x 2.7 x 2.0

Weight (g): 26.7

Meteorite Type: CK4 chondrite

 

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.
