摘    要:坞石垄岩体位于江南造山带与下扬子台坳接合部,沿江南深断裂侵入,岩性由花岗闪长岩和二长花岗岩构成的杂岩体,系燕山晚期同源岩浆不同演化阶段的产物。岩石类型属同熔型花岗岩,具有高硅、富铝、偏碱岩石化学特征,为过铝质钙碱性花岗岩类。与周边同类型太平岩体、洪田都岩体、旌德岩体等相比,Mo、W元素丰度值高。中型规模的萌坑钼矿产于坞石垄岩体中,具有一定的找矿前景。

关 键 词:江南造山带  下扬子台坳  江南深断裂  坞石垄岩体  萌坑钼矿  黄山  皖南

Geological and geochemical characteristics and its prospecting significance of Wushilong intrusion in southern Anhui
Institution:ZHANG Xian-neng, HAO Guo-Sheng( 1. No. 332 Geological Party, Anhui Bureau of Geology and Minerals Exploration, Huangshan 245000, Anhui, China; 2. Anhui Geol- ogy and Mining International Investment Ltd, Hefei 230001, China)
Abstract:The Wushilong intrusion was located in the southern Anhui Province,between Jiangnan orogenic belt and Yangtze platform depression. It was invaded along Jiangnan deep fracture; it was a complex which consisted of both granodiorite and monzonite,representing the various stages of the magma evolution in late Yanshanian. The composition was characteristic of high silicon,rich in aluminum and alkaline,belong to peraluminous calc-alkaline granite type. Compared to similar intrusive bodies in the vicinity Taiping,Hongtian and Jingde intrusions,etc,it was of more high abundance of Mo and W. The medium-scale Mengkeng Mo Mine was occurred in Wushilong intrusion,which was of more potential in Mo deposit exploration.
Keywords:Jiangnan orogenic belt  Lower Yangtze platform depression  Jiangnan deep fracture  Wushilong intrusion  Mengkeng Mo Mine  Huangshan City  Southern Anhui Province
