摘　　要：柏坊铜矿原为沉积砂岩型铜矿,后经构造、地下热卤水作用,部分成为淋滤再造型铜矿。再造型铜矿体主要产在不整合面凹部的砂砾岩中(Ⅳ号矿体)或产在壶天群构造破碎带及岩溶边缘。认为矿区内淋滤再造型矿体多沿老岩溶和新岩溶构造带分布,这两种岩溶与成矿的关系最为密切。The Bofang copper deposit was once a sedimentary sandstone-type copper mine,and then part of it became a leaching-and-recycling-type copper mine due to tectonism and the role of underground thermal brine.Reworking-type ore body mainly lies in the concave unconformity or in the edge of structural fracture zone of Hutian group.This paper mainly discusses the relationship between karst and mineralization on the basis of analyzing ore genesis.
