闽西龙江亭铜矿地质特征及物化探异常找矿标志

Geological characteristics and geophysical and geochemical anomaly prospecting criteria of Longjiangting copper deposit in western Fujian

龙江亭铜矿是闽西武平地区重要的铜矿之一,在其深部及外围有较大的找矿潜力。通过对龙江亭铜矿的地质特征和物化探异常特征的分析并总结找矿标志。研究结果为,该矿床的找矿标志有:绢云母化—硅化—黄铁矿化蚀变组合、视频散率的偏高场及异常场、Cu-Au-Ag-Pb-Zn-Sn-Bi-As-Ba元素晕。该矿床为浅成中低温火山—次火山热液型矿床。

Longjiangting copper deposit is one of the important copper mines in Wuping area of western Fujian,which has great prospecting potential in its deep and periphery.Through the analysis of the geological characteristics and geophysical and geochemical anomaly characteristics of Longjiangting copper mine,the prospecting criteria are summarized.The results show that the sericitization-silicification-pyritization alteration combination,high field and abnormal field of video divergence,Cu-Au-Ag-Pb-Zn-Sn-Bi-As-Ba element halo are prospecting indicators of the deposit.The deposit is a shallow medium-low temperature volcanic-subvolcanic hydrothermal deposit.
