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

Possible missing speciesFormulaMatch %Due to recorded presence of
QuartzSiO285.79%Arfvedsonite (60.53 %), Zircon (64.02 %)
AegirineNaFe3+Si2O664.63%Arfvedsonite (64.64 %)

Key: Mineral matches key element mineralogy of deposit Key element(s) in mineral not listed for deposit (-20% score)


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.
