The Pellapahk Cu-Mo and Oleninskoe Au-Ag deposits in the western segment of Russian Arctic Kolmozero–Voronya greenstone belt are considered two parts an Archean (2.83–2.82 Ga) porphyry-epithermal system, probably oldest one defined Fennoscandian Shield. Formation deposit at epithermal stage system is indicated by spatial genetic relationships with sills granite porphyry, geochemical association...

Abstract Porphyry Mo deposits are important suppliers of molybdenum for industrial applications, but the origin and source metals in these remain debated. Here, we present isotope data Miocene mineralized porphyritic monzogranites (MPMs) Paleocene barren biotite tuffs (BMTs) from Bangpu porphyry (Cu) deposit Gangdese metallogenic belt. The results show that MPMs display radiogenic Sr Pb isotope...

The trace element composition of detrital magnetite grains recovered from six local streams around the Casino high-grade porphyry Cu-Au-Mo deposit, west-central Yukon, is compared with igneous and magmatic-hydrothermal mineralized unmineralized host rocks at deposit. Linear discriminant analysis 12 elements (Mg, Al, Ti, V, Mn, Co, Cr, Ni, Cu, Zn, Ga Ge) plots Ti versus Ni/Cr are used to discrim...

Volatile-rich intermediate to silicic magmatic systems can feed devastating volcanic eruptions but also generate valuable magmatic-hydrothermal ore deposits that supply most of the world's copper. Understanding geometry, dynamics and timescales these is critical in developing models for predicting occurrence future large eruptions. Here, we use zircon petrochronology from an equigranular monzon...
