Abstract The Tamusu deposit is a large sandstone-type uranium deposit discovered in recent years in the Bayingobi basin, Inner Mongolia. Hydrothermal activity was recorded by veins in this deposit, but its relationship with uranium mineralization has not been clarified. In this study, petrographic observations, chemical composition of U minerals, whole rock geochemistry, fluid inclusions and C-O-S stable isotope studies of sandstone and veins were integrated to characterize the mineralizing flui...

Abstract The Dianfang gold deposit, located in the Xiong’ershan–Waifangshan region within the southern margin of the North China Craton, consists of eastern and western ore blocks, which are hosted in the Dianfang breccia pipe and Paleoproterozoic volcanic rocks, respectively. The eastern ore block, which occurs within the southern and hanging wall margins of the Dianfang breccia pipe and in fractures in the rhyolites of the Jidanping Formation, consists of rhyolite-hosted and breccia-hosted dis...

Abstract The giant Shizhuyuan W–Sn–Mo–Bi–Pb–Zn polymetallic skarn-type deposit, which lies in the world-famous Nanling W–Sn metallogenic belt, has a close affinity with the Qianlishan granite complex. Previous studies focused on the Qianlishan granitoids rather than relevant skarns, where the evolutionary processes of skarn-forming fluids, mineralized fluids and sources of metals are debated. This study carried out systematic EPMA and LA-ICPMS zircon U–Pb dating, major- and trace-element and Lu–...

Abstract Serra Pelada is a high-grade hydrothermal Au - Pd - Pt deposit within the Carajas mineral province, eastern Amazon craton, which shows an exceptional metal enrichment at carbon-enriched hosted ores (> 1000s ppm Au+Pt+Pd). The main orebody is structurally hosted at the hinge of a recumbent syncline, consisting of dolomitic metasandstones at the outer part of the fold, a layer of carbonaceous metasiltstone in which most orebodies are located, and red siltstone in the core of the fold. Dis...

Abstract Guqiong is an Ag–Au polymetallic deposit located in the eastern part of the Au–Sb ore belt along the Indus-Yarlung Zangbo suture in the North Himalaya. In this study, we have identified three major alteration/mineralization stages for Guqiong based on the mineral assemblages and their paragenetic relationships, namely the (I) pre-ore alteration, forming mainly ore-barren thick quartz veins and vuggy quartz; (II) main ore stage that comprises quartz veins with sulfide mineralization incl...

Abstract Canadian Malartic is a large-tonnage, low-grade Archean gold deposit (16.3 Moz, 1.08 g/t Au) located in the Abitibi region of Quebec, Canada. A large part of the mineralization is hosted in the Pontiac Group metasedimentary rocks, which consist of mudstones to greywackes at upper greenschist to amphibolite facies. In exploration and production environments, these lithologies are challenging to characterize by conventional core logging methods, while in a research setting thin section-si...

Abstract There are many Neoarchaean orogenic gold hosting greenstone belts in the Dharwar Craton (DC), India; among them the southern extension of the Kolar greenstone belt (SKGB) contain promising gold deposits such as Chigargunta and Bisanatham. Auriferous laminated quartz-calcite veins are hosted mainly within the sheared and altered Champion gneiss and amphibolite in Chigargunta and Bisanatham respectively. The hydrothermal alteration mineral assemblages show three main alteration zones at C...

Abstract The relationship between gold mineralization and magmatism within the Youjiang Basin of SW China remains poorly constrained as a result of the lack of outcropping igneous units in this region. This study presents new geological, geochronological, and geochemical data for recently discovered dolerite dykes associated with the Nibao gold deposit, which is located within the NW Youjiang Basin of SW China. Zircon laser ablation–inductively coupled plasma–mass spectrometry (LA–ICP–MS) U–Pb d...
