Late Silurian A-type granite is reported for the first time in the Wulonggou gold district,eastern segment of the Kunlun orogenic belt.This paper presents(1)laser ablation inductively coupled plasma mass spectrometry(LA-ICP-MS)U-Pb agefor the Wulonggou A-type granite to determine precisely the time of the magmatism,(2)geochemical,Nd and Hf isotope data for the Wulonggou A-type granite to constrain the petrogenesis and tectonic setting.The LA-ICP-MS U-Pb analyses of zircon from the Wulonggou A-type granite y...
