The boundaries of new quartz grains of dynamical recrystallization, which are well-developed in two phases of felsic tectonite, had statistically self-similarity with microscopic features, such as indented or embayed boundary shape. Their area-perimeter fractal dimensions range from 1.097 to 1.144 with the range of deformation temperatures from 600 to 700℃, which is corresponding to granulite facies of metamorphic condition. The strain-rates calculated by rheologic empirical equation are less than 10^-7.27s^-1, and that of the later protomylonite associated with mafic brittle-ductile shear zone is less half order of magnitude than that of early mylonite in main-ductile shear zone. The area-perimeter fractal dimension of quartz grains has earlier been proposed as a strain-rate gauge based on experimental deformation of the quartz aggregates, however this method of fractal analysis has rarely been used to estimate the strain-rate of naturally deformed rocks. In comparison with analysis of other estimation methods, it was concluded that geothermometer proposed by Kruhl is suitable, while the strain-rate equation proposed by Takahashi can be only suitable for lower deformation temperature (T<400℃)., authors=LI Zhensheng, TIAN Xiaoli, ZHANG Wenjun, TAO Ye, authorsList=LI Zhensheng;TIAN Xiaoli;ZHANG Wenjun;TAO Ye, authorCompany=School of Resources and

articleAbstract=安徽桐城挂车河镇(挂镇)地区东西向韧性剪切带包括早期长英质韧性主剪切带、晚期镁铁质韧-脆性剪切带和伴生的长英质同向或牵引变形带.两期长英质构造岩中石英动态重结晶新颗粒发育,边界具有锯齿状或港湾状等不同的微观特征,具有统计意义上的自相似性和明显的分形特征.其分形维数介于1.097~1.144,变形温度介于600~700℃,变形条件相当于麻粒岩相和同构造花岗岩;高温流变学方法估算应变速率低于10^-7.27s^-1,镁铁质韧-脆性剪切带伴生初糜棱岩的应变速率比主韧性剪切带糜棱岩的小0.5数量级左右.分形维数可用作变形温度计和应变速率计,但石英颗粒变形实验推导的Kruhl温度计和Takahashi应变速率计在天然变形岩石中应用很少.与其他方法估算的变形温度和应变速率综合对比结果表明,Kruhl温度计是适用的,而Takahashi应变速率计仅适用于低温(T<400℃)条件.,
