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
31 : Thermally altered carbonate, phosphate, and iron formations50
40 : Regional metamorphism (greenschist, amphibolite, granulite facies)43
