Predictive Mineralogy

Possible unrecorded species at Fenglin W-Cu deposit, Dongxiang Co., Fuzhou, Jiangxi, China

This table is based on statistical analysis of other localities containing similar species to the ones found at this locality.

Possible missing species	Formula	Match %	Due to recorded presence of
Malachite	Cu₂(CO₃)(OH)₂	90.82%	Chalcocite (56.20 %), Covellite (54.66 %), Emplectite (53.79 %)
Silver	Ag	50.31%	Acanthite (50.32 %)
Gold	Au	43.17%	Wittichenite (53.97 %)

Predicting paragenetic modes of deposit

Green indicates almost certain match based on minerals unique to a certain deposit type. Yellow indicates a possibly poor match, but should not be entirely discounted. Scores > 100 indicate strong confidence.
