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.

34 : Complex granite pegmatites	50
26 : Hadean detrital minerals	28
35 : Ultra-alkali and agpaitic igneous rocks	28
31 : Thermally altered carbonate, phosphate, and iron formations	23
9 : Lava/xenolith minerals (hornfels, sanidinite facies)	23
24 : Authigenic minerals in terrestrial sediments (see also #17)	5
19 : Granitic intrusive rocks	5
