横山岭铅锌矿床围岩岩性单一,经找出特殊标志层进行坑道地质填图后,揭示了该矿床复杂的褶皱—断裂系统,其主体为横山岭背斜,又被一系列褶曲和断裂切割而复杂化,而北北东向和北东向构造叠加是矿床的控矿构造。文中阐述了这两组构造的矿化和分带特征,划分了控矿构造类型,对控矿构造的演化问题,也作了初步的探讨。
The Yanshanling Pb-Zn deposit is characterized by a single lithologic rock. After the excavation of the special geological map of the tunnel, the complex fold-fracture system of the deposit is revealed. The main body is the Hengshanling anticline and is also subjected to a series of folds and faults Cutting and complicated, while the north-north east and northeast tectonic superimposition is the ore-controlling structure of the deposit. In this paper, the mineralization and zonation characteristics of these two groups of structures are explained, the types of ore-controlling structures are divided, and the evolution of ore-controlling structures is also discussed.
