help identify epidote or clinizoisite

0 votes

This mineral is from the Shigar Valley in Pakistan. It is labeled as epidote/clinizoisite with diopside. I asked the dealer if it was epidote or clinozoisite and he said he didn’t know. Does anyone know how to determine the true identify of these?alt text

I think these two minerals are too similar chemically in certain circumstances to visually identify without x-ray analysis. In certain localites either epidote or clinozoisite will dominate, so it can be determined by locality, but these pakistan epidotes/clinozoisite are very hard to visually identify.
