Weight (g): 1041.0

Meteorite Type: CK4 chondrite


Macroscopic Description: Robbie now EET92002 is a heart-shaped carbonaceous chondrite that is covered with dull, black fusion crust. The fusion crust is considerably thicker on the bottom surface. Abundant light-green evaporite deposit is present on three surfaces. Numerous chondrules are protruding from the exterior surfaces. The interior matrix is dark gray and has a massive texture.


Thin Section (,7) Description: Brian Mason

The section shows an aggregate of small (0.01-0.05 mm) olivine grains and minor opaque material, with occasional chondrules up to 1.5 mm across. Olivine composition is Fa32; a little diopside, Wo44Fs6, and plagioclase, An52, were analyzed. The opaque material is largely magnetite. The meteorite is a C4 chondrite of the Karoonda subtype; it may be paired with the EET87507 group.
