Weight:
357 g
Place:
Antarctica
Collection Date:
1992
Notes:
The specimen has a shape suggestive of a giant arrowhead, with cm-sized regmaglypts. Its dark brown color is due to a coating of terrestrial iron oxides. Small patches of fusion crust remain in surface depressions, and delicate streamers of late-stage, ablation-formed layered melt-crust are preserved at edges of adjoining surfaces. Occasional cm-long, narrow incisions several mm deep are present, possibly formed by ablation melting of schreibersite inclusions. A 52 g slice was removed 6.5 cm from the 'point of the specimen and perpendicular to the long axis. Butts of 357 g and 1954 g resulted. Suggestions of a Widmanstätten pattern (WP) were apparent on the cut surface.
