摘　　要：综合运用地质学、地球物理学等多学科方法,对云南省景谷县民乐镇曾家村铜矿展开深入探究。通过全面分析区域地质背景与大量勘探数据,明确东矿段南段矿体主要呈似层状、透镜状及细脉状产出,赋存于白垩系景星组特定层位。含矿岩性多样,铜矿物以斑铜矿、辉铜矿为主,次为黄铜矿,伴少量砷黝铜矿,偶见硫砷铜矿、铜蓝。矿体特征受地层层位严格制约,与地层产状基本一致。研究判定该铜矿为沉积-改造型,是早期含铜地质体经后期构造叠加改造,于白垩纪地壳振荡上升时期形成[1]。同时,经构建三维地质模型、开展地球物理反演等多维手段剖析东矿段北段深部成矿潜力,认为其深部具备可观的成矿潜力与资源储量,为后续铜矿勘探与开发提供了关键依据。This study comprehensively applies interdisciplinary methods such as geology and geophysics to conduct in-depth exploration of the Zengjia Village copper mine in Minle Town,Jinggu County,Yunnan Province.Through a comprehensive analysis of the regional geological background and a large amount of exploration data,it is clear that the ore body in the southern section of the eastern ore block is mainly produced in a layered,lens shaped,and vein shaped manner,occurring in specific layers of the Cretaceous Jingxing Formation.The ore bearing rock types are diverse,with bornite and chalcopyrite as the main copper minerals,followed by chalcopyrite,and a small amount of arsenopyrite,occasionally accompanied by chalcopyrite and chalcopyrite.The characteristics of the ore body are strictly constrained by the stratigraphic layer and are basically consistent with the geological occurrence.The study determined that the copper mine is of sedimentary alteration type,formed during the Cretaceous period of crustal oscillation and uplift after the early copper bearing geological body underwent structural superposition and alteration in the later stage.At the same time,by constructing a three-dimensional geological model and conducting geophysical inversion and other multidimensional methods to analyze the deep mineralization potential of the northern section of the East Mine,it is believed that the deep part has considerable mineralization potential and resource reserves,providing a key basis for subsequent copper exploration and development.
