滁县铜矿床储量前景预测

PREDICTION OF POTENTIAL RESERVE OF THE COPPER DEPOSIT IN CHUXIAN

滁县铜矿床为安徽东部的一个伴生金的中型铜矿床，矿体严格受燕山期岩体与寒武系奥陶系灰岩接触带控制。在研究铜矿体分布规律、铜矿石类型及磁异常特征的基础上，预测南部接触带１５线至１８线磁异常及铜矿化集中地段，其下部有大的热源体存在。在其“漏管”下部两侧“肩部”的有利构造部位，为矽卡岩铜矿体的产出地段。

The copper deposit in Chuxian,located in east Auhui province,is a middle size of copper orebody coexisting with gold.The orebody is strictly controlled by the contact zone of Yanshan rocks and limestones of and O.On the basis of studying distribution regalation of the copper orebody,types of copper minerals and the magnetic signature,it is prodicted that there would be a large thermal resource under the area of range from southern contact zone,i.e. line No.15,to the concentration belt of magnetic signature and copper mineralization,i.e.line No.18,and there would be a scarn type of copper orebody located under the favorable tectonic site,which may be of potential reserve of large size of goldCopper ore deposit.
