摘要
文章通过研究虎形山地区稳定同位素,以及采用含矿石英Rb-Sr同位素测年方法,测得虎形山钨铍多金属矿、石滚岭铜多金属矿和张家冲铜多金属矿的成矿年龄分别为135±5Ma、144±5Ma、127±16Ma,而幕阜山岩体的年龄为147.9±5Ma,同属燕山晚期。笔者认为,虎形山地区矿床的形成与燕山晚期岩浆、构造活动有关,主要成矿物质来源于深部隐伏侵入的岩浆。
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 de- posit and Zhangjiachong Cu polymetallic deposit are ascertained to be 135±SMa, 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 metal- logenic materials originate from the deep-concealed-intrusive magma.
