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 formations

Unique: Lazurite

5 : Primary asteroid phases

Unique: Fluoro-richterite
