Predictive Mineralogy

Possible unrecorded species at American Mine, Eureka Mining District, Grant County, New Mexico, USA

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

Possible missing speciesFormulaMatch %Due to recorded presence of
MalachiteCu2(CO3)(OH)289.75%Chalcocite (56.20 %), Olivenite (76.60 %)
AzuriteCu3(CO3)2(OH)266.37%Olivenite (66.38 %)

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.
