摘要
贵州六盘水地区存在多组不同方向的构造带。前人从不同观点出发,对它们的相互关系和形成机理提出过不同的解释。本文认为这些构造带的组合符合一定的几何规律,构成由“郎岱三角形构造”、“晴隆孤形构造”、“盘县三角形构造”和“发耳菱形构造”等组合成的一种统一的区域构造格局,受到复杂边界条件的控制。本文分析了六盘水地区的古构造发展和动力作用,计算了三角形块体的构造应力场。六盘水地区的矿产资源丰富,本文为该区的构造控矿问题的分析提供了一种新的理论基础.
There are many tectonic belts, trending in different direction in Liuzhi-Panxian-Shuicheng region. The relationship among them and deformation mechanism have been explained from some different viewpoints. We consider that the association of those belts conform to a certian grometric regularity They form an united regional tectonic formework, which consist of 'Langdai triangle', 'Qinglong arc', 'Panxian triangle',and'Faer rhombus'. They are controlled by complex boundary condition.
In this paper the paleotectonic develop and dynamic action in the region are analysed, the tectonic stress field of trigonal block is calculated There are rich mineral re sources in Liuzhi-Panxian-Snuicheng region. This treatise provide a new theoretical basis for analysing structure control of ore deposits in the region.
