Lithocaps are composed of silicic and advanced argillic altered rocks, and represent an important target for porphyry-epithermal Cu-Au exploration. Previous studies showed that integrating alunite spectral and composition with lithocap whole-rock geochemistry can effectively aid exploration for conc...
