Writeup from AMN 7(2):
Sample No.: EET83230 Location: Elephant Moraine Field No.: 1330 Weight (gms): 530 Meteorite Type: Ataxite
Physical Description: Roy S. Clarke, Jr. This roughly equidimensional 5.5cm x 5.0cm x 3 cm rounded individual is reminiscent of a small cobble. It is completely covered with a secondary reddish-brown coating of iron oxides, and no indication of fusion crust remains. The surface that has been recently exposed to wind ablation in our atmosphere is slightly smoother than the other surfaces, having rounded edges and a slightly distorted rectangular outline.
Tentative Classification: Roy S. Clarke, Jr . A slice through one side of the specimen produced a 15cm2 surface for examination. The matrix is martensitic, containing a few widely dispersed kamacite spindles. An occasional spindle will contain a very small schreibersite. The section's most interesting feature is a concentration in one half of the slice of about a dozen mm-sized iron phosphate crystals, some with euhedral outline and/or enclosed troilite. These inclusions are partially bordered by thin kamacites. | ||||||||||||||||||||||||
