Abstract The Baguamiao gold deposit, located in the Fengxian-Taibai ore district, is one of the largest gold deposits in the West Qinling orogen, central China. The poor age constraints on the gold mineralization event at the Baguamiao has caused strong debate on ore genesis and associated geodynamic controls. We carried out Sm-Nd and 40Ar-39Ar geochronological studies to determine more precise age constraints on the god deposition. The gold mineralization at Baguamiao deposit was developed duri...

Abstract The Eastern Qinling ore belt is the second largest Au province in China and is estimated to contain more than 1300 metric tons of Au. Most of the gold deposits in the belt are vein-type (fracture-hosted Au). Whether they are of metamorphic origin or magmatic-hydrothermal origin is controversial. The Qiyugou Au orefield developed granite-hosted Au, breccia pipe-hosted Au, and fracture-hosted Au, and the present study investigates these three types of gold mineralization. New zircon U–Pb ...

The type, association, variations, and valence states of several metal elements of scheelite can trace the source and evolution of the ore-forming fluids. There are four types of scheelite from the Xiaoyao deposit: (1) scheelite intergrown with garnet in the proximal zone (Sch1a) and with pyroxene in the distal zone (Sch1b), (2) scheelite replaced Sch1a (Sch2a) and crystallized as rims around Sch1b (Sch2b), (3) quartz vein scheelite with oscillatory zoning (Sch3), and 4) scheelite (Sch4) within ...

Abstract Zircon U–Pb dating and in-situ Hf–O isotopic compositions, combined with whole-rock geochemical and Sr–Nd isotope data, are systematically presented to constrain the timing and petrogenesis of the late Mesozoic granitoids in eastern Guangdong Province, SE China. Zircon U–Pb chronology shows that two intrusions were emplaced from the Middle Jurassic to Early Cretaceous (166–144 Ma). All the granitoids are classified as calc-alkaline I-type granites with highly diverse elemental and isoto...

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 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 ...
