摘　　要：铜陵桥头杨地区位于新屋里向斜北东段,铜陵矿集区凤凰山矿田和沙滩脚矿田之间,作为向斜构造区深部找矿靶区重点验证区,深部发育有较完整的石炭系、二叠系和三叠系有利成矿层位和岩浆岩,深部发现的矽卡岩、隐爆角砾岩及矿化特征与姚家岭式热液型铅锌矿床成矿要素吻合。钻探验证和激电测井成果显示,研究区深部音频大地电磁测量(AMT)低阻异常区具有较大找矿潜力。The Qiaotouyang area in Tongling is located in the north east section of Xinwuli syncline,between the Fenghuangshan ore field and the Shatanjiao ore field.As a preferred verification area in the deep ore prospecting targets in the syncline structure,there exists carboniferous system,Permian system and Triassic system stratums and magmatic rocks in the deep.The skarn and cryptoexplosive breccias found in the deep showed the same metallogenic factors with the Yaojialing ore deposit in the type of hydrothermal deposit.Combined with the drilling and induced polarization logging,it was concluded that there are great prospecting potential in the deep audio magnetotelluric survey(AMT)low resistance abnormal area in the deep of the syncline structure.
