Whole-rock geochemical data and compositional balance analysis (CoBA), combined with a magnetic susceptibility model obtained from high-precision survey, are useful exploration tools in the Jiama porphyry–skarn deposit, southern Tibet, China. In this paper, three innovative aspects of described that have assisted deposit: an improved geological understanding thrust–nappe structure, hydrothermal...

the base (cu–pb–zn) and precious metals (ag±au) mineralization at the no. 4 anomaly of golojeh deposit occurred in volcanic and sub–volcanic eocene–oligocene host rocks, in the central part of the tarom–hashtjin zone. basic to intermediate volcanic, volcaniclastic and sub–volcanic rocks are dominated in the area and include andesite, basaltic andesite, trachy-andesite, dacite and tuff with affi...

The Poplar copper-molybdenum porphyry deposit, 50 kilometres south-southwest of Houston, is centred near 54 degrees 01 minute north and 126 degrees 50 minutes west. The property is accessible from Houston via 80 kilometres of forest access roads along the Morice River, Owen Lake, Tahtsa Reach, and Poplar Lake. The deposit is situated on the northeast shore of Tagetochlain (Poplar) Lake in an ar...

The Sungun  copper  porphyry deposit is hosted by a Tertiary magmatic complex in  the  Azarbayjan province , northwestern Iran. The  Sungan mine  in its southern and eastern parts is limited  by early Miocene volcanic and by Late Cretaceous limestone rocks in northern and eastern parts respectively . The Sungun  deposit is associated with a suite of porphyritic granitoids and late dikes intrudi...

he Boddington Au-Cu mine is located in the southwestern corner of the Yilgarn craton in the Western Gneiss terrane in Western Australia. The mineralization is hosted in the northern part of the Saddleback greenstone belt which includes an early sequence of basaltic to dacitic volcanic rocks and associated shallow level porphyry intrusions emplaced between ~2714-2696 Ma. After two periods of def...

The Huoluotai Cu (Mo) deposit is a recently discovered porphyry in the northern Great Xing’an Range, NE China. Fluid inclusion (FI) micro-thermometry results and C–H–O–S–Pb isotope compositions of are presented this study. ore-forming process consists sulfide-barren quartz stage (I), + chalcopyrite ± pyrite molybdenite (II), polymetallic sulfide (III), calcite fluorite (IV). mineralization occu...

The mid-Proterozoic (ca. 1850–850 Ma) is a peculiar period of Earth history in many respects: ophiolites and passive margins this age are rare, whereas anorthosite A-type granite suites abundant; metamorphic rocks typically record high thermobaric (temperature/pressure) ratios, ultrahigh pressure (UHP) rare; the abundance economic mineral deposits features rare porphyry Cu-Au abundant Ni-Cu Fe-...
