Predictive Mineralogy

Possible unrecorded species at Faieto quarry, Sant'Andrea Bagni, Medesano, Parma Province, Emilia-Romagna, Italy

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
QuartzSiO289.35%Melanophlogite (73.33 %), Opal (60.07 %)
CalciteCaCO353.33%Melanophlogite (53.33 %)

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.
