广域电磁法在辽东新房金矿深部勘查中的应用
Application of the wide-field electromagnetic method in the deep exploration of the Xinfang gold deposit,eastern Liaoning Province
摘要
Abstract
The Xinfang gold deposit resides in the gold polymetallic ore concentration area in eastern Liaoning Province.Based on re-gional metallogenic patterns and existing exploration results,the southern part of the Yalu River fault zone,where the Xinfang gold de-posit is located,shows significant potential for gold resources.As exploration progresses,more gold ore bodies are expected to be dis-covered in the gold deposit area.However,the lack of effective deep exploration techniques limits further exploration and exploitation in the area,failing to effectively reveal the extensions of lithological boundaries and the distributions of fault structures in the area.This study presented the first application of the wide-field electromagnetic method in the area.Based on the obtained results and geological engineering information,this study delineated the electrical layers within a depth of 3 km,determining the thickness of the Neoprotero-zoic cap rocks and inferring several fault zones.Combined with existing geological data,this study identified the low-resistivity anomaly zone at a depth of about 1 km as an extensional structural plane caused by ductile shearing.Overall,this study provides valuable geo-physical data for establishing a geological prospecting model for eastern Liaoning Province,holding significant research value for geolog-ical and mineral exploration in the area.关键词
