辽宁清原地区铜锌矿床找矿标志及找矿方向

PROSPECTING CRITERIA FOR COPPER-ZINC DEPOSITS IN QINGYUAN,LIAONING PROVINCE

摘要: 清原太古宙花岗-绿岩地体中块状硫化物铜锌矿床具海底火山喷发作用控矿、沉积作用控矿、裂谷槽盆构造控矿、褶皱构造控矿特征.分析建立了薄层互层带、穹隆体外缘、褶皱脊线、垂向二导零值线、TEM异常及K₂O/Na₂O比值、卤族元素异常、汞异常等综合找矿标志.最后提出了探边、摸底、攻深、找盲的找矿方向.

Abstract: The ore control factors of the massive sulfide Cu-Zn deposits in Qingyuan Archeozoic granite greenstone include submarine volcanic eruption, sedimentation, taphrogeosyncline structures and folding.The comprehensive prospecting criteria are established in such aspects as thin interbedded belts, dome borders, fold axes, zero lines of vertical secondary derivation, TEM anomalies, K₂O/Na₂O value, bulogen family element anomalies, mercury anomalies and so on.
