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
32 : Ba/Mn/Pb/Zn deposits, including metamorphic deposits	50
22 : Hydration and low-𝑇 subsurface aqueous alteration (see also #23)	50
49 : Oxic cellular biomineralization (see also #44)	1
47h : Low-𝑇 subaerial oxidative hydration, weathering (see also #16 and #23) - [Near-surface oxidized, dehydrated minerals]	1
