摘要
研究区大地构造属于秦祁昆造山系柴北缘结合带,构造岩浆活动强烈,成矿地质条件较好。本文对研究区地层、构造、岩浆岩及围岩蚀变进行详细分析,进而对控矿因素与找矿标志进行研究,矿区成因类型为构造蚀变岩型金矿,石英脉、构造、围岩蚀变等多种找矿标志明显,研究结果对同类矿床勘查具有重要的参考。
The tectonic structure of the study area belongs to the combination zone of the northern margin of the Qaidam Basin of the Qinqikun orogenic system,with strong tectonic magmatism and good metallogenic geological conditions.This paper makes a detailed analysis of the strata,structure,magmatic rock and wall rock alteration in the study area,and then studies the ore-controlling factors and ore prospecting markers.Various ore prospecting signs such as alteration are obvious,and the research results have an important reference for the exploration of similar ore deposits.
