摘要
构建庐枞地区燕山期Fe、Cu、Au成矿系列,根据成矿构造背景和含矿岩浆岩特点,将其划分为3个成矿亚系列:以矽卡岩型Cu、Mo、Au矿为主的亚系列,以矽卡岩型Fe及Fe、Cu矿为主的亚系列和以玢岩铁矿为主的火山--次火山岩型铁矿亚系列。该区具较大找矿远景的靶区有:①沙溪铜(金)找矿靶区;②清水塘—岳山铁、锌找矿靶区;③井边—巴家滩铜矿找矿靶区。其中,井边—巴家滩地区成矿地质条件良好,深部存在斑岩型铜矿的可能性较大,具有寻找大型斑岩型铜矿的找矿远景,应对该区进行深入研究和普查评价工作,以实现庐枞盆地内部铜矿找矿的突破。经预测,应对泥河、罗河和龙桥等大型超亿吨铁矿外围进行勘探,以达到建立20～25亿吨大型钢铁基地的目标。
The authors made clear on the Fe,Cu and Au metallogenic series of Yanshanian in Luzong area and divided it into three metallogenic sub-series based on structural background of mineralization and characteristics of ore-bearing magmatic rocks,including the sub-series mainly by skarn-type Cu,Mo and Au deposits,the sub-series mainly by skarn-type Fe and Fe,Cu deposits,and the sub-series of igneous and sub-igneous rock iron deposit mainly by porphyrite iron deposits.The prospecting target areas in Lujiang-Zongyang areas are：① Shaxi copper（gold） prospecting area;② Qingshuitang-Yueshan iron and zinc prospecting area;③ Jingbian-Bajiatan copper deposit prospecting area.The Jingbian-Bajiatan area has pretty good geological situation of mineralization with very large probablility of existing porphyry copper deposit in its deep part and prospecting perspective of porphyry copper deposit,which is necessary to do further research and evaluate for breakthrough of copper deposit prospecting in Luzong Basin.Based on the prediction,the periphery exploration of Nihe,Luohe and Longqiao large super-billion tons iron deposits should be carried out,so as to reach the main goal of building 2～2.5 billion tons steel and iron base.
