Predictive Mineralogy

Possible unrecorded species at Pyant Gyi mine (Pyan Gyi), Pein-Pyit (Painpyit; Pyan Pyit), Mogok Township, Pyin-Oo-Lwin District, Mandalay Region, Myanmar

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
35 : Ultra-alkali and agpaitic igneous rocks

Unique: Johachidolite, Poudretteite
