Predictive Mineralogy

Possible unrecorded species at Gongguan-Huilong ore field, Xunyang County, Ankang, Shaanxi, China

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

Key: Mineral matches key element mineralogy of deposit Key element(s) in mineral not listed for deposit (-20% score)


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.
