澜沧老厂超大型银铅多金属矿床是产在晚古生代裂谷火山岩中的多因复成矿床，本文通过对老厂矿田滑脱构造的研究，指出了滑脱构造普遍存在于该区中上石炭统一下二叠统巨厚层状灰岩和下石炭统火山岩之间，它是大陆地壳伸展构造的一种类型，具有其独特的地质特征，其形成与裂谷演化后期区域伸展作用和深部岩浆物质底辟作用有关。老厂矿田的银铅多金属成矿作用与滑脱构造有密切的成因联系，滑脱构造带直接控制了重要工业矿体的产出。 The Lancang old plant The super-large silver-lead polymetallic deposit is a multi-factor complex ore deposit produced in late Paleozoic rift-type volcanic rocks. Based on the study of the slipping structure in Laochang ore field, it is pointed out that the slippage structure is widespread in the middle- It is a type of extensional structure of the continental crust that is characterized by its unique geological features. It is consistent with regional extensional effects of the late rift evolution and deep magmas The role of material diapause. The silver-lead-polymetallic mineralization in Laochang ore field is closely related to the slippage structure, and the slippage tectonic belt directly controls the output of important industrial ore bodies.
