| 摘 要： | 地球是一动态系统,其各层圈的构造运动归根到底就是多矿物复合岩石在各种物理条件(例如,温度、围压、差应力、应变速率、应变方式等)下和化学环境(例如,氧逸度和水含量)中的形变。流变学作为研究岩石力学性质和变形行为的科学,现已成为地球动力学和构造地质学的支柱学科。本文对国际上近年来岩石流变学的最新进展做些扼要的介绍,呼吁中国固体地学界加强流变学的研究,做出经得起时间淘洗、实践检验的原创性成果来,使中国的构造地质学研究迈进国际先进的行列。 |

| Abstract: | The Earth is an integrated, dynamic system whose tectonic processes (e.g., mantle convection, mountain building, ocean forming, deep continental subduction and exhumation, crustal channel flow, earthquakes) are largely controlled by the rheological behavior of polymineralic rocks. Breakthroughs in the understanding of deformation mechanisms, composite mechanics and seismic properties and in the development of innovative technologies for multi-scale observations, quantitative measurements, analogue and numeric models have taken rheology as one of the most active new frontiers of solid Earth sciences during the last decade. The Chinese community of structural geology, tectonics and geodynamics has reached a critical time to face exciting opportunities and challenges for research. The aim of this article is to emphasize rheology as a research topic of top priority and to critically overview some important aspects: high-temperature and high-pressure deformation experiments, in-situ investigations of deformation processes, analogue modeling, and numeric simulation. We hope that the scientific workforce of the nation can be built to advance our understanding of continental tectonics and geodynamics through detailed and comprehensive studies of the rheology of continental crust and mantle rocks. |
