Petrogenesis, Magma Source and Tectonic Setting of the Yaozhuang Granitoids in Northern Qinling Belt, Central China: Constraints From Zircon U–Pb Geochronology, Whole‐Rock Geochemistry and Sr–Nd–Hf Isotopes

Bin Zhou, Gongwen Wang, Yi Cao, Liandang Zhao et autres

ABSTRACT The Yaozhuang granitoids are located in the Northern Qinling Belt (NQB) and consist mainly of coarse‐grained monzogranite, medium‐grained biotite granite, granite porphyry, and diorite porphyry. Zircon U–Pb dating, geochemical, and Sr–Nd–Hf isotope analyses were carried out to constrain the age, petrogenesis, …

Geology and fluid evolution of the Shuangqing skarn copper deposit in the Eastern Tianshan

Liandang Zhao, Xiao‐Tong Zheng, Wanjian Lu, Shuanliang Zhang

The Central Tianshan Block, located in the southern Central Asian Orogenic Belt, hosts Precambrian basement rocks, Paleozoic arc-related granitoids, and a variety of significant deposits. These deposits generally underwent tectonic or magmatic deformation or overprinting, which led to their ore genesis and …

Geology, fluid inclusions, and H–O–S isotopes of the Yaozhuang Pb–Zn deposit in the Northern Qinling Belt, Central China

Xiao‐Tong Zheng, Jiangang Jiao, Liandang Zhao, Bin Zhou

• The Yaozhuang Pb–Zn deposit has three alteration/mineralization stages. • Medium-temperature, low-salinity magmatic–hydrothermal fluids contributed to mineralization. • It is a Late Mesozoic hydrothermal vein-type deposit related with porphyry system. The genetic relationship between distal Pb–Zn–Ag vein-type deposits and porphyry molybdenum systems …

Tectonic setting, mineralization, and ore geochemistry of the Paleozoic IOCG deposits in Xinjiang, NW China

Shuanliang Zhang, Liandang Zhao, Pei Liang, Hongjun Jiang et autres

• Xinjiang IOCG deposits formed in Paleozoic magmatic arc and basin inversion settings. • Basin inversion-hosted IOCG show significant non-magmatic fluid involvement. • External fluids, including sulfur, compensated for magmatic deficiencies in copper-gold mineralization. The Paleozoic iron oxide copper–gold (IOCG) deposits in …

Using combined texture-element-isotope indicators of sulfides to trace fluid mixing and evolution in Paleozoic IOCG system

Shuanliang Zhang, Georges Beaudoin, Liandang Zhao, Lin Gong et autres

Geochemistry of sulfides is widely used to constrain sources and ore-forming processes of various mineral deposits. However, its application on Fe–oxide Cu–Au (IOCG) deposits is not well constrained due to multiphase pyrite and Cu minerals and their complex inheritance relationships. The Shuanglong …
