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
33 : Minerals deposited by hydrothermal metal-rich fluids (see also [#12]) Unique: Boulangerite, Bournonite, Fülöppite, Plagionite, Zinkenite	100
47d : Low-𝑇 subaerial oxidative hydration, weathering (see also #16 and #23) - [Arsenates, antimonates, selenates, bismuthinates]	8
47a : Low-𝑇 subaerial oxidative hydration, weathering (see also #16 and #23) - [Near-surface hydration of prior minerals]	6
47h : Low-𝑇 subaerial oxidative hydration, weathering (see also #16 and #23) - [Near-surface oxidized, dehydrated minerals]	3
55 : Anthropogenic mine minerals	1
