摘要

那更康切尔沟银矿床是近年来在青海省东昆仑成矿带首次发现的中低温热液型银矿床。在研究区内通过水系沉积物测量、地质填图、土壤测量、激电中梯剖面测量及槽探、钻探等手段,提交了那更康切尔沟大型银矿床。在找矿过程中由找金转为找银,确定找矿方向后,敢于大胆利用钻探进行深部验证并发现厚大银矿体,从而取得寻找银矿的突破。该矿床的发现,改变了以往对青海省东昆仑地区无成型银矿的找矿认识。通过系统总结认为,以矿床产出的有利成矿地质背景结合水系沉积物Ag、Sb、As、Sn、Mn、Cu等元素组成的综合异常HS6进行找矿选区,以典型矿床特征为准则进行勘查方法选择,关键性技术与方法的应用及找矿思路的创新是那更康切尔沟银矿床发现和勘查过程中的主要启示。
        The Nagengkangqieergou Silver Deposit is a medium-low temperature hydrothermal silver deposit first discovered in the East Kunlun metallogenic belt of Qinghai Province in recent years. Through the engineering control of stream sediment survey,geological mapping,soil survey,IP intermediate gradient profiling measurement and trench exploration,and drilling,Nagengkangqieergou large-scale silver deposit was submitted. In the process of prospecting,the changing from gold to silver has been made. After determining the prospecting direction,the prospectors dare use drilling to conduct deep verification and discover thick and large silver deposits,thus making a breakthrough in prospecting for silver deposits. The discovery of this deposit has changed the previous understanding of prospecting for nonformed silver deposits in the East Kunlun area of Qinghai Province. Through systematic summary,it is concluded that prospecting areas are selected in combination with the favorable metallogenic geological background of ore deposits and the comprehensive anomalous HS6 of stream sediments combining Ag,Sb,As,Sn,Mn and Cu. The selection of prospecting methods is based on the typical characteristics of ore deposits. The application of key techniques and methods and the innovative understanding of prospecting ideas are the main enlightenment from the discovery and exploration of Nagengkangqieergou Silver Deposit.
