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
47b : Low-𝑇 subaerial oxidative hydration, weathering (see also #16 and #23) - [Sulfates and sulfites]	50
45a : Oxidized fumarolic minerals (see also [#11]) - [Sulfates, arsenates, selenates, antimonates]	50
50 : Coal and/or oil shale minerals	38
47a : Low-𝑇 subaerial oxidative hydration, weathering (see also #16 and #23) - [Near-surface hydration of prior minerals]	33
49 : Oxic cellular biomineralization (see also #44)	30
