摘要:
乔木湾地区位于青阳—南陵县凹陷盆地南部,目前在该区及周边地区已发现金属矿床(点)十余处,具有良好的金、钨、铜、锑、银矿找矿潜力。在1∶5万乔木湾幅水系沉积物测量成果的基础上,以田屋—车山一带为研究区,对区内Au、Ag、Cu、Pb、Zn等12种元素的地球化学特征进行研究。通过分析元素地球化学参数特征及元素组合特征,发现Au、Ag、Sb、Hg元素在研究区具有富集成矿的可能,为研究区主要成矿元素。在以Au为主的单元素异常的基础上,根据元素组合特征及异常特征,结合异常所处的成矿地质条件,共圈定6处地球化学综合异常,划分出4个找矿远景区,即车山找矿远景区、田屋找矿远景区、金山找矿远景区、栗阳找矿远景区,对远景区内的地质成矿条件进行了概述,为该区下一步找矿工作提供了重要依据。
Abstract:
The Qiaomuwan area is located in southern Qingyang-Nanling depression basin. At present, more than ten metal deposits (occurrences) have been discovered in this area and surroundings with good prospecting potentials of gold, tungsten, copper, antimony and silver deposits. Based on the 1:50 000 stream sediment survey in Qiaomuwan area, this paper described geochemical characteristics of 12 elementssuch as Au,Ag, Cu, Pb, Zn, etc. in the Tianwu-Cheshan study area. According to the element geochemical parameters and element assemblage, there are favorable potentials for the concentration and mineralization of Au, Ag, Sb and Hg which are main ore-forming elements in the study area. With single element anomaly map of Au as its priority, combined with elements assemblages, abnormal characteristics and the ore-forming geological settings, the authors delineated 6 geochemical comprehensive anomalies and 4 metallogenic prospective areas, including Cheshan, Tianwu, Jinshan and Liyang prospects, and introduced geological metallogenic settings of the prospective area, which can provide important evidences for further prospecting work.
