莱阳盆地北缘西涝口金矿区北接触带激电异常特征及成矿潜力评价

西涝口金矿区累计提交金资源量5 t多,已发现矿脉矿体主要集中在荆山群地层与鹊山岩体的南接触带附近。该文通过对荆山群地层与鹊山岩体北部开展研究,分析北接触带激电异常,认为北接触带激电异常可能是由金盲矿体引起,成矿条件好,成矿潜力大,应进一步开展工作。

Characteristics of Induced Polarization Anomalies and Evaluation on Mineralization Potentiality in North Contact Belt of Xilaokou Gold Deposit in Northen Part of Laiyang Basin

Cumulative amount of gold resources in Xilaokou gold deposit can reach more than 5t. Already found ore veins and ore bodies are mainly concentrated in southern contact zone of Jingshan group.Through study on strata of Jingshan group and rocks in northern Queshan, and analyzing induced polarization anomalies in northern contact zone, it is regarded that the induced polarization anomalies in northern contact zone may be caused by the gold blind ore bodies. The ore-forming conditions in this area are good with large mineralization potentiality. Thus, further exploration work should be carried out in this area.
