摘要
柏坊铜矿是一个以沉积为主,后经地下水淋滤改造的铜矿床。其成矿与白垩系及构造作用密切相关,层状矿体赋存在白垩系的长石石英砂岩中,古基底上隆部位、古岩溶及近东西向穿层断裂控制着扁豆状、囊状矿体的分布。且矿体赋存标高具有"东浅西深"的分布规律。在分析矿床地质特征和成矿规律的基础上,对成矿模式进行了探讨。
Bofang Copper Mineral deposit belongs to depositing - reworking type, which is firstly stem- med from sedimentation then reworking and enriching through the leaching affect of ground water. The mineralization is closely related to the Cretaceous strata and tectonics. Applying the regularity that ore bodies＇location were controlled by the topography of old basement under Cretaceous strata and carst, the distributing rule of ore bodies were revealed, and then the prospecting direction was carried out.
