Improving Mindat.orgJordanite epitaxy on pyrite?

29th Nov 2017 16:47 UTCJeff Weissman Expert

Today's POTD (https://www.mindat.org/photo-345670.html) caption states that this is an epitaxy of jordanite on pyrite. I fail to see any crystallographic relationships between the jordanite and pyrite crystals. Perhaps "overgrowth" would be a more appropriate descriptor?

Note that there are several images for jordanite at the Fantiscritti Quarry with this issue, none appear to show a true epitaxial relationship.

Agreed, I can only see one image that looks potentially epitaxial, still possibly fortuitous.
