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
47a : Low-饾憞 subaerial oxidative hydration, weathering (see also #16 and #23) - [Near-surface hydration of prior minerals]

Unique: Ajoite, Plancheite, Shattuckite

23 : Subaerial aqueous alteration by non-redox-sensitive fluids (see also #47)

Unique: Papagoite

47c : Low-饾憞 subaerial oxidative hydration, weathering (see also #16 and #23) - [Carbonates, phosphates, borates, nitrates]61
