Predictive Mineralogy

Possible unrecorded species at Bluebird Kyanite Mine (Vitrefrax Corporation property; Vitrefrax Mine; Bluebird Hill Kyanite deposit; Drifted Snow; Foster Bluebird Mine; Bluebird Mine; Ogilby Kyanite deposit), Vitrefrax Hill (Bluebird Hill), Obregon, Cargo Muchacho Mining District (Hedges Mining District; Ogilby Mining District), Cargo Muchacho Mountains, Imperial County, California, USA

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
