官庄—沙坪一带金矿地质特征及找矿预测
|
摘要
官庄—沙坪一带位于雪峰山弧形构造带由北东向到近东西向的转折部位,金矿资源丰富,成矿地质条件优越,找矿前景良好。文章在论述沃溪金—锑—钨多金属矿床地质特征的基础上分析了区域金矿成矿规律,总结了金矿控矿要素,建立了该区金矿成矿模式和预测模型。结合1∶5万水系沉积物地球化学异常特征,开展了矿产预测,并对今后矿产勘查工作提出了建议。
The area along Guanzhuang-Shaping is located in the turning point of Xuefeng mountain arc tectonic zone turning from NE into nearly EW,with abundant of gold resources,superior ore-forming geological conditions and good prospecting potential.Based on the disscusion of the geological characteristics of the Woxi Au-Sb-W polymetallic deposit,this paper analyzed the regional metallogenic regularities and got a conclusion about the controlling factors of Au deposits and extablished the metallogenic and prediction models for Au deposits in this area.Combing with the characteristics of geochemical anomalies of 1:50000 stream sediments,the paper carried out prediction for mineral resources and put forward suggestions for future mineral exploration in this area.
