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
40 : Regional metamorphism (greenschist, amphibolite, granulite facies)50
31 : Thermally altered carbonate, phosphate, and iron formations50
39 : High-𝑃 metamorphism (blueschist, eclogite, ultrahigh 𝑃 facies)5
22 : Hydration and low-𝑇 subsurface aqueous alteration (see also #23)3
43 : Shear-induced minerals (including mylonite/slickensides)3
8 : Mafic igneous rocks2
16 : Low-𝑇 aqueous alteration of Hadean subaerial lithologies (see also #23)2
7 : Ultramafic igneous rocks1
37 : Layered igneous intrusions and related PGE minerals1
23 : Subaerial aqueous alteration by non-redox-sensitive fluids (see also #47)1
