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.

35 : Ultra-alkali and agpaitic igneous rocks	50
9 : Lava/xenolith minerals (hornfels, sanidinite facies)	45
45a : Oxidized fumarolic minerals (see also [#11]) - [Sulfates, arsenates, selenates, antimonates]	44
