Abstract Paleo-to Neoarchean granitoid gneisses (ca. 3.30 to 2.49 Ga) are well preserved in the Western Superior Craton. Protoliths of these gneisses are mainly I-type granitoids characterized by high Sr/Y and La/Yb ratios and low Mg#, consistent with Archean tonalite-trondhjemite-granodiorites. Zircons from granitoid gneisses commonly contain three growth phases: inherited cores (zircon I), magmatic rims (zircon II) and outer rims that have undergone Pb-loss (zircon III). The 3.12 Ga to 2.86 Ga...

In the past decade, significant research efforts have been devoted to mineral chemistry studies to assist porphyry exploration. These activities can be divided into two major fields of research: (1) porphyry indicator minerals (PIMs), which are used to identify the presence of, or potential for, porphyry-style mineralization based on the chemistry of magmatic minerals such as zircon, plagioclase and apatite, or resistate hydrothermal minerals such as magnetite; and (2) porphyry vectoring and fer...

Abstract A combination of zircon U Pb ages, whole-rock geochemistry, Sr Nd isotopes, and in situ zircon Hf isotope, for newly found felsic igneous rocks from the Hongshanliang copper deposit district in the Aqishan-Yamansu belt, NW China, are presented to investigate the petrogenesis and tectonic or even crustal evolution of the Eastern Tianshan during the Late Paleozoic to the Early Mesozoic. Zircon U Pb ages show two phases of igneous activity in the Early Carboniferous (348.8 ± 2.1 Ma and 343...

The Tuwu porphyry Cu deposit, located in Eastern Tianshan, NW China, is hosted by a plagiogranite porphyry and Carboniferous Qi’eshan Group volcanic rocks. Based on crosscutting relationships and mineral assemblages, hydrothermal alteration and mineralization processes at Tuwu can be divided into four stages: early propylitic alteration (stage I), porphyry mineralization (stage II), overprinting mineralization (stage III), and post-mineralization (stage IV). The porphyry mineralization stage (st...

Abstract Magnetite in the Devonian Yuleken porphyry Cu–Mo deposit located in NW China witnessed complicated magmatic-hydrothermal ore-forming processes. The magnetite grains can be divided into MagI-A (from the Beitashan Formation basalt), MagI-B (from the porphyritic syenite wall rock), MagII (from sodic-calcic alteration zone), MagIII-A (from early potassic stage with no concomitant sulfides) and MagIII-B (from late potassic alteration coexisting with sulfides). Although magnetite crystals of ...

Abstract Although garnet U Pb dating method has been reported recently, yet the accurate concordia 206Pb/238U ages and growth histories of multi generation of garnets based on ages were still lacked. LA-ICP-MS U Pb dating on multi-generational grandite (grossular-andradite) garnet from the large Tonglvshan Cu-Fe-Au skarn deposit was applied in this study. Based on petrographic observation, in chronological order, three generation garnets have been distinguished, namely homogeneous Grt1-exo (in t...

The Atlas porphyry Cu–Au deposit is located in central Cebu Island in the Philippines, with a proven mineral reserve of 1420 Mt at 0.45% Cu, 0.24 g/t Au, 0.018 g/t Mo, and 1.8 g/t Ag. It is associated with the Lutopan quartz diorite porphyry stock that was emplaced into the Cretaceous volcano-sedimentary sequences of the Cansi Formation. Two stages of hypogene alteration have been identified at Atlas: stage I quartz–magnetite ± chalcopyrite ± pyrite veins associated with potassic and propylitic ...

Abstract Colloform pyrite with core-rim texture is commonly deposited in carbonate platforms associated with the sulfide ores such as the Caixiashan Pb–Zn deposit. However, the genesis of colloform pyrite in Pb–Zn deposits, its growth controls and their geological implication are insufficiently understood. Integration of in-situ trace element and SIMS sulfur isotopes has revealed geochemical variations among these pyrite layers. These colloform pyrite occur as residual phases of core-rim aggrega...
