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.

Paragenetic ModeScore
33 : Minerals deposited by hydrothermal metal-rich fluids (see also [#12])

Unique: Rucklidgeite, Safflorite, Tsumoite

31 : Thermally altered carbonate, phosphate, and iron formations

Unique: Hörnesite
