Predictive Mineralogy

Possible unrecorded species at Wind Valley (Vento Valley), Prettau (Predoi), Puster Valley District, South Tyrol, Trentino-Alto Adige (Trentino-South Tyrol), Italy

This table is based on statistical analysis of other localities containing similar species to the ones found at this locality.

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
23 : Subaerial aqueous alteration by non-redox-sensitive fluids (see also #47)50
40 : Regional metamorphism (greenschist, amphibolite, granulite facies)40
19 : Granitic intrusive rocks31
31 : Thermally altered carbonate, phosphate, and iron formations31
34 : Complex granite pegmatites27
26 : Hadean detrital minerals10
