The Hongniu-Hongshan porphyry-skarn deposit is located in the southern Yidun terrane Sanjiang Tethyan Metallogenic Domain (STMD). Although its metallogenesis has been well constrained past decade, magmatic processes for granitoids are still poorly understood. Herein, we provide new geochemical data on minerals (plagioclase, amphibole, and clinopyroxene) to get a better insight into these proces...

1. Introduction Thompson-Okanagan-Cariboo is an administrative region in south-central BC, established after the province reorganized its natural resource agencies in 2010. Mining predates Confederation and today, the region is home to fi ve of BC's largest metal mines, several industrial mineral mines, and many small placer operations, gravel pits, and rock quarries. power), and skilled worker...

To construct copper heap leaching structures, a stepped heap of ore is placed over an isolated sloping surface and then washed with sulphuric acid. The isolated bed of such a heap consists of some natural and geosynthetic layers. Shear strength parameters between these layers are low, so they form the possible sliding surfaces of the heaps. Economic and environmental considerations call for stu...

In order to improve our understanding of the mineral potential of northern Vancouver Island beyond the wellknown intrusion-related Cu-Au-Ag(-Mo) porphyry deposits (e.g., Hushamu, MINFILE 092L 240 and the former Island Copper mine, MINFILE 092L 158) and base and precious-metal skarns (e.g., Merry Widow, MINFILE 092L 044), we need a better understanding of the stratigraphy of the Bonanza island a...

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...

Large albitite bodies associated with explosive brecciation, fenite aureoles, intrusive carbonate rocks, olivine dolerites, and copper mineralization are described from the Dead Sea rift region in the south-eastern Sinai Peninsula. The main carbonate phases comprise breunnerite and dolomite with actinolite the main phase in the fenites. Field and isotopic evidence indicates that the intrusive c...

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...
