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 Mode	Score
47a : Low-𝑇 subaerial oxidative hydration, weathering (see also #16 and #23) - [Near-surface hydration of prior minerals] Unique: Tungstite	103
33 : Minerals deposited by hydrothermal metal-rich fluids (see also [#12]) Unique: Wittichenite	100
31 : Thermally altered carbonate, phosphate, and iron formations	19
40 : Regional metamorphism (greenschist, amphibolite, granulite facies)	14
26 : Hadean detrital minerals	5
34 : Complex granite pegmatites	4
53 : Other minerals with taphonomic origins	4

6 : Secondary asteroid phases	1
50 : Coal and/or oil shale minerals	1
36 : Carbonatites, kimberlites, and related igneous rocks	1
