Abstract The Tantou Au deposit is a large-scale gold deposit in the Xiong’ershan area. A geochemical study of pyrite was conducted using laser ablation inductively coupled plasma mass spectrometry. Two types of hydrothermal pyrite were identified in the ores and wall rocks, i.e., the fine euhedral pyrite in brecciated ores (Py1) and coarse grains disseminated in the quartz-sulfide veins (Py2). The trace elements of the two pyrite types exhibit different concentrations, associations and rim-core ...

Earth’s atmosphere experienced a step of profound oxygenation during the Neoproterozoic era, accompanied by diversification of animals. However, during the Cryogenian period (720–635 million years ago) Earth experienced its most severe glaciations which likely impacted marine ecosystems and multicellular life in the oceans. In particular, large volumes of Mn and Fe accumulated during the interglacial intervals of the Cryogenian glaciations, indicating large anoxic marine metal reservoirs. Here w...

Abstract Tungsten deposits related to weakly fractionated granitoids are scarce worldwide. The geological significance of early Paleozoic magmatism and associated mineralization in South China remains poorly understood compared with well-documented Mesozoic magmatism and related mineralization. Early Paleozoic magmatic rocks, previously thought to be only rarely associated with mineralization, crop out widely in the Dayaoshan area, South China, and have significant prospecting potential for tung...

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 South China Block (SCB) is one of the largest W-Sn-polymetallic metallogenic district over the world, with most of the deposits formed during the Mesozoic. The Early Jurassic of SCB was considered as a magmatic and metallogenic quiescence stage, as response to the tectonic transition from the paleo-Tethyan to the paleo-Pacific geodynamic domains. The Dading Fe-Sn deposit is a quite rare Early Jurassic deposit recognized in SCB. SIMS Zircon U–Pb and molybdenite Re-Os dating indicate ...

The Gutaishan deposit is a slate-hosted lode Au–Sb deposit in the Xiangzhong Sb–Au metallogenic province, South China. The deposit has a proven reserve of ca. 9 -t gold at an average grade of 13-g/t and contains 2500-t Sb. The deposit represents the product of a complex ore-forming process, comprising four different stages, of which the third stage is the main gold–stibnite bearing stage. Scanning electron microscopy, electron probe microanalysis, and laser ablation inductively coupled plasma-ma...
