贵州省旋涡构造特征

The Spiral Tectonic Features of Guizhou

本文首次将“全球旋涡大地构造假说”用于具体地区的地质构造研究。从理论上分析了地幔旋涡对流作用在岩石圈旋涡构造单元内的应力分布。提出中国大陆的不同方向、不同性质、看似繁复的褶皱断裂构造,均可用东亚旋涡构造单元的旋转向心运动得到统一、合理的解释。贵州境内大规模的强烈褶皱和断裂变形以及多种形象的构造组合形式和不同的变形结果,综合地表现出了旋涡构造单元的典型区域构造特征。结合贵州特征初步探讨了“全球旋涡大地构造假说”在大地构造研究、成矿预测、地震预报等方面的理论与实际意义。

This paper, for the first time, uses 'The Hypothesis of Global Spiral Tectonic 'to study geotec-tonic of certain regions, analyses theoretically the stress distribution of mantle's spiral convecting action in lithological spiral tectonic elements and puts forward different directions and features of China continent. It seems that complex faults and rift structures can be unified and explained by spiral centripetal movement of the spiral tectonic elements in East Asia. The intense faults and rift deformations on large scale, composition forms and different deformation results in Guizhou comprehensively show typical regional tectonic features of spiral tectonic elements. According to these features, the paper deals with the theoretical and practical significance of 'The Hypothesis of Global Spiral Tectonic' in geotectonic research, ore-forming prediction and seismic prediction.
