摘要
官岭下地属于福建省蒲城县山下镇官岭下村,地质上崇安-蒲城地区华竹坑火山盆地东南部边缘,区内火山岩热液活动频繁,尤其是侏罗系晚期火山的构造岩浆活动强烈,形成了较多铀、钼多金属成矿的含矿主岩-酸性火山岩。工作区内官岭下断裂是一条北东向长期活动的构造岩浆活动带,也是一条大型的逆冲推覆构造,该构造早期控岩、控盆,晚期控矿,目前在构造带下盘火山岩中发现了较好的工业铀矿体及大量异常,通过进一步工作预测深部找矿空间存在富大矿体。
Guanlingxia belongs to Guanlingxia Village,Shanxia Town,Pucheng County,Fujian Province.Geologically,at the southeast edge of Huazhukeng volcanic basin in Chong an Pucheng Area,volcanic hydrothermal activity in the area is frequent,especially the tectonic magmatic activity of volcanoes in the late Jurassic is strong,forming acidic volcanic rocks with more uranium,molybdenum and gold mineralization.Guanlingxia fault in the working area is a long-term tectonic magmatic activity zone in northeast direction and a large thrust nappe structure.The structure controls rock,basin and ore in the early stage and late stage.At present,good industrial uranium ore bodies and a large number of anomalies have been found in the volcanic rocks in the footwall of the structural belt.Through further work,it is predicted that there are rich and large ore bodies in the deep prospecting space.
