Abstract:

岩石圈的流变学分析和岩石构造、显微构造证据揭示出大陆岩石圈具有显著的横向和纵向上的异向性,并具有明显的非板块表现.全面开展不同温度和压力条件下变形岩石的构造与显微构造分析,正确认识岩石圈不同层次上岩石的流变学规律、流动机理及其制约因素等,将成为后板块构造研究与新的岩石圈演化理论建立的基础和主要动力.岩石流动的宏观-微观尺度问题(岩石圈结构与流变性、边界弱化效应和岩石流变学与显微构造响应等)、岩石流动的时间问题(不同时间尺度岩石的流动性、实验室模拟与天然岩石流动的协调性、浅层岩石流动变形的有效定年等)、岩石流动的制约因素(内在的成分与结构、外在的物理与化学环境)将成为岩石圈流动与岩石变形显微构造研究的重要方面.现代化实验室建设和最新实验技术、手段的利用将成为解决上述科学问题的必要条件.
