摘要
研究区位于黑龙江省东南部,完达山-太平岭有色金属、贵金属成矿带内。该区赋矿岩石为花岗闪长岩和二长花岗岩,受古太平洋板块的俯冲作用,岩浆活动频繁,为金矿形成提供了有利的地质、构造背景条件。为进一步分析找矿潜力,本文在已有金矿床研究基础上,开展了1∶1万地质、物探、化探测量工作,其中土壤地球化学测量结果显示,Au变异系数高,是主要成矿元素;电、磁测量结果显示,成矿有利地段表现出正负磁异常伴生、低阻高极化的特征。经综合分析认为该区具有寻找金矿的潜力。
The study area is located in the southeastern part of Heilongjiang Province,within the Wanda Mountain-Taipingling metallogenic belt for non-ferrous and precious metals.Due to the subduction of the ancient Pacific Plate,magmatic activities were frequent.The ore-bearing rocks in this area are mainly granodiorite and adamellite,providing favorable geological and tectonic background conditions for the formation of gold deposits.To further analyze the potential for mineral exploration,based on the existing research on gold deposits,1∶10000 geological,geophysical,and geochemical surveys were carried out.The results of soil geochemical surveys show that Au has a high coefficient of variation and is the main ore-forming element.The results of electrical and magnetic surveys indicate that favorable areas for mineralization exhibit the characteristics of co-occurring positive and negative magnetic anomalies,as well as low resistivity and high polarization.Through comprehensive analysis,it is believed that this area has potential for gold exploration.
