着重探讨了澜沧老厂银铅矿田基本构造特征，对矿田内发育的褶皱构造、断裂构造、推覆构造、滑脱构造、基底（断裂）构造和火山构造等进行了较为全面的论述；首次提出了该区存在较大规模的滑脱构造，并对其特点、形成机制及其与成矿的关系作了深入的探讨，解决了该矿田长期以来悬而未决的成矿构造问题。针对该矿床存在三种不同类型的矿体群，从控矿构造的角度出发，分别论述了不同时代、不同类型和不同层次的构造对矿体的控制作用。运用大比例尺遥感技术，对该区的火山机构进行解译和精确定位，首次提出在老厂地区存在一个大型火山活动中心－老厂火山洼地，老厂矿床受大型火山洼地中次级喷火口控制的观点。最后，从构造演化历史出发，对构造与成矿的关系作了较为系统的概括。
This paper focuses on the basic structural features of the Lancang old factory silver-lead ore field and makes a comprehensive discussion of the fold structure, fault structure, nappe structure, slippage structure, basement (fault) structure and volcano structure developed in the ore field. It is proposed that there is a large-scale slippage structure in this area, and its characteristics, formation mechanism and its relationship with metallogeny are discussed in depth, which solves the problem of the ore-forming structure that has been pending for a long time. There are three different types of ore bodies in this deposit. From the point of view of ore-controlling structure, the author discusses the control effects of different ages, different types and different levels of structures on ore bodies. Using large-scale remote sensing technology to interpret and pinpoint volcanic structures in the area, it is proposed for the first time that there exists a large volcano activity center-Lao Factory volcanic depot in Lao Chang area. The Lao Chang deposit is controlled by the secondary jet in large volcanic depressions the opinion of. Finally, from the history of tectonic evolution, the relationship between tectonics and mineralization is systematically summarized.
