To characterize mineral assemblages and geochemical compositions in advanced argillic-altered rocks in British Columbia.
Analyzed mineral assemblages across three locations in British Columbia.
Used petrographic and short-wave infrared analysis for alteration zoning.
Mapped alteration zones with whole-rock geochemical data and K-Mg-Al molar diagrams.
Applied trace element indices to compare mineral concentrations above and below porphyry deposits.
Identified distinct mineral zoning from distal green muscovite to proximal kaolinite-dickite assemblages.
Described aluminum-rich minerals prevalent in central alteration zones.
Developed indices that correlate alteration mineralogy with presence of mineral deposits.
