摘要
In the paper,by studying the stable isotopes in Huxingshan area and using the Rb-Sr isotopic dating methods,the mineralization ages of Huxingshan W-Be polymetallic deposit,Shigunling Cu polymetallic deposit and Zhangjiachong Cu polymetallic deposit are ascertained to be 135±5Ma,144±5Ma and 127±16Ma respectively,and the age of Mufushan rock mass is 147.9±5Ma which falls in late Yanshanian.The formation of Huxingshan deposit is related to magma and tectonic activity of late Yanshanian.The principal metallogenic materials originate from the deep-concealed-intrusive magma.
