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
35 : Ultra-alkali and agpaitic igneous rocks50
9 : Lava/xenolith minerals (hornfels, sanidinite facies)46
31 : Thermally altered carbonate, phosphate, and iron formations46

36 : Carbonatites, kimberlites, and related igneous rocks6
40 : Regional metamorphism (greenschist, amphibolite, granulite facies)6
