Abstract Porphyry-type deposits are the main global source of copper and molybdenum. An improved understanding most favorable structural settings for emplacement these is necessary successful exploration, particularly considering that future discoveries will be made under cover based on conceptual target generation. A common view porphyry preferentially emplaced in pull-apart basins within stri...

structural analysis of remotely sensed data provides a method of assessing the structural significance of large-magnitude regional metallogenesis in the kerman porphyry cu belt in the southern part of the central iranian volcanic belt. the role of large-magnitude ring structures in the distribution of hydrothermal alteration zones and porphyry copper deposits in the southern part of the kerman ...

this study deals with the 3d recovering of magnetic susceptibility model by incorporating the sparsity-based constraints in the inversion algorithm. for this purpose, the area under prospect was divided into a large number of rectangular prisms in a mesh with unknown susceptibilities. tikhonov cost functions with two sparsity functions were used to recover the smooth parts as well as the sharp ...

Demingding is a promising porphyry Mo-dominated deposit recently discovered in the eastern Gangdese metallogenic belt Tibet, China. We present zircon U-Pb-Lu-Hf isotopic studies, as well geochemical data of late monzogranites and prior rhyolites from to uncover their origin geodynamic mechanism. Zircon U–Pb dating yielded precise crystallization ages 17.3 ± 0.6 Ma (MSWD = 2.5) 186.5 3.0 2.0) fo...

In our previous study on petrogenesis of quartz syenite and granite porphyry, the host rocks Late Mesozoic Shapinggou Mo deposit in Qinling–Dabie orogenic belt, we found that initial Sr isotopic composition is strongly affected by degree K-alteration. Here, provide further evidence their minerals to investigate geochemical behaviour trace elements isotopes during alteration explain phenomenon d...

We report the iron (n = 13), copper sulfur 25) and lead 31) isotope compositions of mineralized samples from porphyry, skarn epithermal mineralization in Yenice region that lies east Biga Peninsula, Turkey. The vast majority isotopic data were analyzed world-class Arapuçandere Pb-Zn-Cu (Ag-Au) deposit is one best example intermediate sulfidation deposits within Serbo-Macedonian-Rhodope metallog...

This article describes the geology and industrial mineral potential of corundum, pyrophyllite and andaluite at the Empress deposit in the Taseko Lakes area (Figure 1). The Empress is a copper-goldmolybdenum porphyry deposit located 225 kilometres north of Vancouver and 50 kilometres northwest of Goldbridge and the Bralorne mining camp. Fine-grained corundum, in association with andalusite-pyrop...

studies of three selected sulfide-silicate assemblages from ore samples from the sar cheshmeh porphyry copper deposit led to some ore genetic conclusions. the presence of chalcopyrite blebs in the groundmass orthoclase and quartz from the stock suggests liquid immiscibility in a cooling late-magmatic melt. this is in favor of the orthomagmatic model proposed for porphyry copper deposits. the pr...
