Hematite ps. Pyrite
As recorded:
Guadalupe Mountains, Eddy County, New Mexico, USA
33mm x 33mm x 28mm
Hematite replacing cubic pyrite crystals. Though pseudomorphs after pyrite are far from uncommon, these exhibit complex growth forms, including "thumbprint" hillocks, curved faces, and striations, that make them exceptional above the rest. The specimen shows some contacting on the reverse.
