阳新县欧阳山矿区铜矿地质特征及找矿方向研究OACHSSCD

The Ouyangshan mining area is located in the main contact zone along the southwestern margin of the Yangxin intrusive complex.Ore bodies are mainly hosted in the contact zone between marble xenoliths and quartz diorite,as well as in structural fracture zones within the inner contact zone.Skarn alteration is closely related to mineralization and serves as a direct prospecting indicator in the area.Based on the results of regional prospecting work in the surrounding areas of Ouyangshan,it can be seen that the main ore bodies of the Ouyangshan deposit are controlled by fault-contact composite structures,with dip extensions significantly greater than strike extensions.In particular,the marble xenolith hosting No.II ore body shows no tendency of pinching out at depth,indicating that the No.II ore body still has considerable potential for deep extension and exploration.
