摘要
总结了近十年来岩石扩散蠕变显微构造鉴别特征、研究方法的最新进展。矿物颗粒大小和流体 (包括熔体和水 )等是影响扩散蠕变的重要因素。扩散蠕变与位错蠕变和超塑性变形有密切关系 ,它的研究对大陆裂谷化过程、大陆碰撞带中岩石圈地幔强度弱化。
The newest development of microstructure features and observation and research methods of diffusion creep of rocks in the past ten years are briefly summarized.Grain size of minerals and fluid (including melt and water) are the important factors that affect diffusion creep,ivhich is found to have close relationship with dislocation creep and superplastic deformation.Study on diffusion creep of rocks has important implications for process of continental rifting,strength weakening of lithosphere mantle in continental collision belts,strain localization of ductile shear zones in middle to lower crust and reduction of grain size of minerals with relation to phase transition.
