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	100
35 : Ultra-alkali and agpaitic igneous rocks	16
36 : Carbonatites, kimberlites, and related igneous rocks	11
17 : Marine authigenic Hadean minerals (see also #24)	10
53 : Other minerals with taphonomic origins	7
47c : Low-𝑇 subaerial oxidative hydration, weathering (see also #16 and #23) - [Carbonates, phosphates, borates, nitrates]	7
26 : Hadean detrital minerals	6
34 : Complex granite pegmatites	6
40 : Regional metamorphism (greenschist, amphibolite, granulite facies)	5
31 : Thermally altered carbonate, phosphate, and iron formations	5
32 : Ba/Mn/Pb/Zn deposits, including metamorphic deposits	4
