五十年来中国小型构造研究的回顾与展望

Review of Studying of Mesoscopic Structures in China in Recent 50 Years

50年来我国小型构造的研究从对单个形态的几何学描述发展到对区域构造的全方位、多尺度、多层次、多体制和多世代的综合解析。研究的进展主要表现在:对构造形态和方位的系统分析;定量分析和物质平衡原理在构造分析中应用;对地壳流变学的研究和从构造的力学分析到构造体制分析等方面。与地球物理、地球化学、变质地质学和地质年代学等多学科的配合极大地促进了构造地质学的发展。初步形成了解析构造学的理论体系和方法学。文中还指出了当前在构造研究中的不足和今后的努力方向。

The studying of mesoscopic structures in China has developed from the simple geometrical description of single structural elements to a synthetical analysis of regional structures from the viewpoint of multiple scales, levers, regimes and generations of structures in recent 50 years. The main progresses in the studying of mesoscopic structural geology in recent years are as follows: the systematic analysis of geometry and orientation of structures; the application of quantitative analysis and the principle of balance in structural analysis; the studying of the rheology of crust and the mechanical analysis to regime analysis of regional structures. The cooperation of multiple braches, such as geophysics, geochemistry, geochronology and metamorphic geology, has greatly promoted the studying of mesoscopic structures. The theoretical system and methods of the analytical structural geology are preliminarily formed. The shortcoming and directions of improvement of structural studying have also been pointed out.
