中文摘要: 文章综述了中国地质学家对旋扭构造研究的历史与成果,也介绍了国外相关研究成果。李四光先生通过四篇论著奠定了旋扭构造的理论基础。在后来的研究和找矿实践、多种模拟仿真新方法试验以及力学解析中进一步丰富了旋扭构造的研究内容,深化了对旋扭构造几何学、运动学特征与动力学机制等的认识,提出了有些旋扭构造是螺旋运动的结果及旋扭构造的形成很可能与地球旋转动力问题有关;特别是在找矿勘探方面取得的成功和经济效益,提高了成矿理论认识的水平。文章最后提出今后研究旋扭构造应注意的问题。
Abstract:This paper reviews the history and progress of geomechanics research on rotation-shear structure in China. It also reflects the relevant research results abroad. J.S.Lee laid the theoretical foundation of rotation-shear structure through four theses. The subsequent research and ore-prospecting practice, as well as a variety of new methods for simulation tests and mechanical analysis, further enrich the research contents of rotation-shear structure, deepen the understanding on rotation-shear structure geometry, characteristics of kinematics and dynamics mechanism, proposing the idea that some rotation-shear structures are the results of spiral motion, and the formation of rotation-shear structure is likely to be related to the Earth rotation dynamics. Especially the success and economic benefit achieved in prospecting and exploration have improved the understanding on metallogenic theory. Finally, the paper puts forward the problems that should be paid attention to in the future study of the rotation-shear structure.
