摘要
竹鸡顶铜矿位于乡城大断裂上盘四道桥—竹鸡顶破背斜与三道桥—青达破背斜复合部位,是义敦岛弧带中段新发现的铜矿床。通过对矿体、矿石、成矿年龄及成矿母岩的地球化学特征的研究,认为竹鸡顶铜矿是在燕山晚期,由于义敦岛弧带碰撞造山后伸展作用而形成的岩浆热液—斑岩型铜矿床;在综合研究的基础上,建立了竹鸡顶铜矿的找矿模型。
Located at the compounding position between Sidaoqiao-Zhujiding fracture anticline and Sandaoqiao-Qingda fracture anticline on the hanging wall of Chengxiang large fault, the Zhujiding copper deposit is recently discovered in the central segment of Yidun island arc belt. Based on a study of geochemical charaeteristics of ore bodies, ores, ore-forming age and parent rocks, the authors hold that the Zhujiding copper deposit is a magmatic-bydrothermal-porphyry type ore deposit formed by the extensional action of Yidnn island are belt after the collision-orogenic movement in late Yanshanian period. An ore-prospecting model for the Zhujiding copper deposit has been established on the basis of integrated research.
