摘　　要：中条山成矿带位于华北克拉通中部造山带南部,分布有著名的铜矿峪型、胡篦型、落家河型、横岭关型等不同成因类型的前寒武纪铜矿床。其中胡-篦型铜矿床主要产于中条群余元下组顶部-篦子沟组底、篦子沟组中部、篦子沟组顶部-余家山组底部。按照与成矿关系密切的蚀变、地层物质组成与构造调查并重的原则,开展1∶5万专题地质填图。地质图图面表达采用地层代码及岩性组成方法,客观地表达了与成矿关系密切的中条群余元下组、篦子沟组和余家上组地层组成与结构。提出了当前中条山前寒武纪铜矿专题地质填图的工作方法及填图单位划分与图面表达的方式,有益于探索中国现阶段成矿地质专题填图的方法。The theory and method of thematic geological mapping for Precambrian copper Deposits in the Zhongtiao Mountain is a focus problem as to how to plan and implement geological mapping smoothly on the basis of basic geological mapping.On the basis of 1:50000 thematic geological mapping,such problems as to genesis of mineral deposit,genetic relationships of different types of copper deposits and structural framework in Zhongtiao Mountain can be easily solved.The metallogenic belt of the Zhongtiao Mountain is located in the southern orogenic belt of the middle part of the North China craton,where there occur the famous Tongkuangyu type,Hu-Bi type,Luojiahe type and Henglingguan copper deposits,in which Hu-Bi type copper deposits are distributed at the top of the Yuyuanxia Formation-the bottom of the Bizigou Formation,the center of the Bizigou Formation,and the top of the Bizigou Formation-the bottom of the Yujiashan Formation.According to the principle that the material composition and structure are closely associated with mineralization,the authors carried out 1:50000 thematic geological mapping.The geological maps are expressed by means of stratigraphic code and lithologic composition,which can objectively express the formation lithology of Yuanyuanxai,Bizigou and Yujiashan formations and structure.The above practice included such means as outcrop observation,mapping unit classification,and graphic expression of map for 1:50000 thematic geological mapping in Zhongtiao Mountain Precambrian copper deposits,and the results obtained provide implications for the present thematic geological mapping.
