Carancas H4/5
Carancas, Puno, Peru
1145hrs, 15 September 2007
This fragment is about 8mm in diameter.
The left end of the piece is a flat, dark, striated slickenside / shock
fracture surface.
A similar feature lies four and a half millimeters to the right of that and
in a parallel plane within the sample.
The right end displays a dark coating that is thicker, roughly textured and
not planar. It looks like fusion crust but might be additional exposed
internal shock material. Some portions appear to overlay slickensides.
