王家堡子菱镁矿区位于虎皮峪—红石砬子复背斜西段(即青城子以西),是辽河群复杂褶皱构造的一部分,矿床明显受构造控制。运用变质岩构造解析的基本原理和方法解析王家堡子矿区特征,本区至少经历了两期变形。第一期以紧密线形褶皱构造为主,第二期以宽缓开阔褶皱构造为主,而矿区岩石发生的急据弯曲(呈卷曲状),则属多期变形作用形成的卷曲向斜构造。前寒武系变质岩系,特别是碳酸盐岩的构造解析,不仅对菱镁矿等矿产的普查勘探具有指导意义,而且对解决地层对比亦有重要意义。
The Wangjiapuzi magnesite area is located in the western section of the Hupeiyu-Hongshi Bangzi anticline (ie west of Qingchengzi) and is part of the complex fold structure of the Liaohe Group. The deposit is obviously controlled by its structure. Using the basic principle and method of pavement metamorphism analysis of Wangjiapuzi mining area, the area experienced at least two deformations. The first phase is mainly composed of tight linear folds and the second is dominated by broad and open folds. The urgent occurrence of rock deformation in the mining area is a curly and oblique structure formed by multi-stage deformation. The structural analysis of Precambrian metamorphic rocks, especially carbonate rocks, is not only instructive for the general exploration and exploration of minerals such as magnesite, but also important for the resolution of stratigraphic correlation.
