Predictive Mineralogy

Possible unrecorded species at Zhaxikang Pb-Zn-Ag-Sb deposit (Zaxikang Pb-Zn-Ag-Sb deposit), Zhaxikang ore district, Cona Co. (Cuona Co.), Shannan Prefecture (Lhokha Prefecture; Lhoka Prefecture), Tibet, China

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
CerussitePbCO396.98%Anglesite (71.56 %), Minium (76.06 %), Smithsonite (55.69 %)
PyrolusiteMn4+O263.98%Manganite (63.98 %)

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.

Paragenetic ModeScore
33 : Minerals deposited by hydrothermal metal-rich fluids (see also [#12])

Unique: Boulangerite, Bournonite, Chalcostibite, Freibergite Subgroup, Robinsonite, Zinkenite
