Petrogenesis and tectonic implications of the quartz diorites and mafic microgranular enclaves in the Asiha gold ore deposit in the East Kunlun orogenic belt: Evidence from zircon U–Pb dating, geochemistry, and Sr–Nd–Hf isotopes
Abstract:Calc‐alkaline granitoid intrusions with abundant mafic microgranular enclaves (MMEs) are widespread in the East Kunlun orogenic belt (EKOB). Here, we present petrological observations, zircon U–Pb ages, whole‐rock geochemical, and Sr–Nd–Hf isotopic data for quartz diorites and the MMEs in the Asiha gold ore deposit in the EKOB, to constrain their petrogenesis and tectonic setting. The laser ablation inductively coupled plasma mass spectrometer 206Pb–238U ages of zircons indicate that the host quartz diorites a… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
