Predictive Mineralogy

Possible unrecorded species at North Wheal Jane (Besore Mine; Wheal Evelyn), Newbridge, Kenwyn, Cornwall, England, UK

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
38 : Ophiolites50
40 : Regional metamorphism (greenschist, amphibolite, granulite facies)44
37 : Layered igneous intrusions and related PGE minerals28
36 : Carbonatites, kimberlites, and related igneous rocks28
