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 ModeScore
47h : Low-𝑇 subaerial oxidative hydration, weathering (see also #16 and #23) - [Near-surface oxidized, dehydrated minerals]
