刘屯金矿床Ⅰ,Ⅱ地段深部找矿预测

PROSPECTING AND PREDICTION AT DEPTH OF SECTIONS Ⅰ AND Ⅱ,LIUTUN GOLD DEPOSIT

刘屯金矿床由刘屯（ Ⅰ） 和金屯（ Ⅱ）两个地段组成。作者通过矿床地质特征、深部地球物理特征、金矿体地球化学异常模式判别及矿体剥蚀程度预测等研究，对刘屯金矿床深部成矿提出了新看法，认为Ⅰ地段矿体已剥蚀到中下部，４０ ｍ 以下矿化尖灭；Ⅱ地段矿体剥蚀至头部，向下有较大延深，可进一步开展深部找矿。

The Liutun gold deposit is composed of section Ⅰ,Liutun and section Ⅱ,Jintun.Based on the research on geologic characteristics,deep geophysical characteristics,model recongnition of geochemical anomalies of gold ore bodies,as well as the erosion level of gold ore bodies,the author proposes that the ore body at section Ⅰ has been eroded to the middle lower part,and the ore body pinches out at depth of 40m,but only the upper part of ore body at section Ⅱ was eroded,and ore body may have greater extension to the depth,and deep prospecting must be performed.
