Brambang is one of the porphyry copper-gold prospects/deposits situated along eastern Sunda arc. This study aimed to understand geological framework, alteration geochemistry and ore fluid characteristics prospect. Fieldworks various laboratory analyses were performed including petrography, microscopy, rock geochemistry, chlorite chemistry inclusion microthermometry. The prospect composed andesi...

Abstract Detailed mineralogical and textural studies, combined with sequential X-ray diffraction geochemical modeling, helped to solve the “copper pitch/wad” enigma in Exótica deposit located downstream of Chuquicamata porphyry copper deposit. Copper pitch wad are essentially chrysocolla co-precipitated Mn oxides, mainly birnessite, as well pseudo-amorphous oxide/oxyhydroxides. Linking mineralo...

Porphyry copper (Cu) systems occur along magmatic belts derived in subduction zones. Our current understanding of their formation is restricted to observations from the overriding plate, resulting a knowledge gap terms processes occurring convergence zones through time. An association between key tectonic and timing location porphyry Cu requires linking geological plate models. We connect evolu...

post-mineralization activities may cause difficulties in the process of ore modeling in porphyry deposits. sungun, nw iran, is one of the porphyry copper deposits, in which dyke intrusions have made ore modeling more complicated than expected. among different kinds of dykes, two types were chosen and the consequent geostatistical analyses were applied on. in this study, simple directional vario...

The northwestern part of the Kerman Cenozoic magmatic arc (KCMA) contains many areas with porphyry copper mineralization. In this research, we used the advanced space-borne thermal emission and reflection radiometer (ASTER) and Enhanced Thematic Mapper plus (ETM+) images of this region to map the distribution of hydrothermally altered rocks, based on their mineral assemblages. The spectral meas...
