U–Pb dating, geochemistry, and Sr–Nd isotopic composition of a granodiorite porphyry from the Jiadanggen Cu–(Mo) deposit in the Eastern Kunlun metallogenic belt, Qinghai Province, China

Geological characteristics, metallogenesis, and tectonic setting of porphyry–skarn Cu deposits in East Kunlun Orogen

“…The Hutouya deposit (E90°48′–91°08′; N36°45′–36°49′) is situated at the northeast part of the Qimantagh Belt (Figure ) and contains a reserve of nearly 1 Mt of Cu, Pb, and Zn with associated Fe and Sn (Zhang et al, ). Previous studies were mainly focused on the geological characteristics and ore genesis (Ma et al, ; Yang et al, ; Zhang et al, ), geochemistry and geochronology of the intrusions (Feng et al, ; Li et al, ; Ma et al, ; Qu et al, ; Zhang et al, ), and ore‐forming fluids and materials (Gao et al, ; Lei et al, ). These researches have confirmed that the Hutouya deposit is a typical skarn deposit related to the Triassic magmatism.…”

“…Previous investigations have studied the porphyry–skarn Cu deposits and obtained a wealth of rock and ore‐forming constraints, including geochronological, geochemical, fluid inclusion, and stable isotope data (e.g., Feng et al, ; Lei et al, ; Li et al, ; Liu et al, ; Ma, Feng, Li, & Shu, ; Yu et al, and references therein). However, only a few papers have been published in the international literature (e.g., Li et al, ; Lu et al, ; Wang et al, ; Zhang et al, ), with most of the characteristics of these deposits solely reported in the Chinese literature.…”

“…He et al () proposed that the Qimantagh area in the EKO had great potential for the exploration of typical porphyry Cu deposits, where it is endowed with the same ore‐forming geological conditions as the giant Qulong porphyry Cu deposit in the Gangdese Belt (Yang et al, ). Although there has been increasing attention on the exploration and research of porphyry Cu deposits in recent decades (Li et al, ; Li et al, ; Song et al, ; Xu, ), whether there are typical giant porphyry Cu deposits in the EKO remains under hot debate.…”

“…However, only a few papers have been published in the international literature (e.g., Li et al, 2015;Lu et al, 2016;Wang et al, 2016;Zhang et al, 2017), with most of the characteristics of these deposits solely reported in the Chinese literature.…”

Middle to Late Triassic granitic magmatism in the East Kunlun Orogenic Belt, NW China: Petrogenesis and implications for a transition from subduction to post‐collision setting of the Palaeo‐Tethys Ocean

“…20,000 km 2 , accounts for 42% of all the magmatic bodies in the EKOB (Mo et al, 2007). In addition, the strong granitic magmatism caused the Triassic porphyry-skarn polymetallic mineralization events (Li, Zhi, et al, 2015). Therefore, the research focused on the granitoids within the EKOB is of great importance in revealing the tectonic evolution and mineralization processes of the Qinghai-Tibetan Plateau.…”
