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.
