摘要
福建胡坊地区位于华夏地块中部北武夷隆起区与南武夷晚古生代坳陷区的交接地带,区内大面积出露志留纪、三叠纪中酸性侵入岩,发育北东东向、北西向断裂,已发现十余处萤石矿床,属岩浆期后热液充填型矿床.在方坑夹、桐坑、维家山、反修桥萤石矿床地质特征分析基础上,开展成矿地质条件分析,圈出岭官—廖厝、雾露坑—莒林、梧地—方坑夹、南金坂—冯厝4个萤石找矿远景区.
Abstract
The Hufang area in Fujian Province is located at the transition of the North Wuyi Uplift area and the South Wuyi Late Paleozoic Depression area in the central part of the Huaxia Block.A large area of Silurian and medium acid intrusive rocks are exposed in the area,with NEE and NW trending faults.More than ten fluorite deposits have been discovered,belonging to the post magmatic hydrothermal filling type deposits.Based on the analysis of the geological characteristics of Fangkengjia,Tongkeng,Weijiashan,and FanxiuQiao fluorite deposits,an analysis of the ore-forming geological conditions was carried out,and four fluorite prospecting prospects were proposed,including Lingguan-Liaocuo,Wulukeng-Julin,Wudi-Fangkengjia,and Nanjinban-Fengcuo.
