贵州省普安县老洞河井田滑脱构造特征及成因分析

Laodonghe Minefield Decollement Structural Features and Genetic Analysis in Puan County, Guizhou Province

老洞河井田褶皱、断裂(含滑脱构造)、滑坡等均有发育。依据地表资料及大量深部钻孔相同层位和断点组合资料、结合滑脱构造理论对本区构造成因进行了综合分析。结果表明:老洞河井田滑脱构造同时具有伸展外来系和重力滑动外来系两个成因类型,这一结论为该区钻井层位追踪对比及断点组合提供了解释依据。

Fold, fauh （including decollement） and landslide have all developed in the Laodonghe minefield. According to surface data, large amount faulted point assembled data in same horizon from deep part exploration drilling, combined with previous theories carried out integral analysis and study on decollement structure genesis. The result has shown that the decollement structures have both extend- ed allochthonous system and gravitational sliding allochthonous system two genetic types, thus have provided geological reference data for mine construction feasibility study and preliminary design henceforth.
