安徽省东至县柴山地区成矿地质条件与找矿潜力浅析OA

The Chaishan area in Dongzhi County,Anhui Province,is situated at the southern margin of the middle-lower Yangtze River metallogenic belt,which is a significant gold and polymetallic mineral enrichment zone in Anhui Province.Through comprehensive analysis of regional geological structures,magmatic rock characteristics and mineralization patterns,along with integration of geophysical exploration anomalies and comparison with typical ore deposits,this paper systematically examines the metallogenic geological conditions of the Chaishan gold-tungsten deposit.The study reveals that the NE-trending Lanchengfan fault zone and the Sangangjian-Yangmeiqiao anticline jointly control magma intrusion and mineralization enrichment,with the Yanshanian granodiorite porphyry serving as the source of heat and material for mineralization.Prospecting potential analysis identifies the secondary structural fracture zones and deep concealed rock bodies as high-priority exploration targets,with strong potential to host significant mineral deposits at the southern margin of the middle-lower Yangtze River metallogenic belt.
