Location Map of Antarctic Falls
The rounded specimen is covered with a dull black fusion crust 1-2 mm thick over post of the surface. Specimen is complete with the exception of one end where a fracture surface covers 1/8 of the specimenís total surface area. The fusion crust has polygonal fractures over most of the exterior surface. In a few places this fusion crust has been broken away revealing a black fine-grained matrix. Specimen shows several large fractures. On the surface neighboring one of these fractures there is a white material which may be an evaporite deposit. The side of the specimen that was in contact with the ice at the time of recovery is slightly reddish. Dimensions: 4.5 x 4.0 x 5.0 cm. Small, irregular white inclusions and several chondrules are apparent on a freshly broken surface.
