摘要
连云山西缘花岗质糜棱岩是湖南长寿街—双牌断裂动热变质带的重要组成部分 .在讨论糜棱岩显微构造特征的基础上 ,利用位错密度法对该断裂带的古差异应力和应变速率进行了估算 ,其结果分别为 80 MPa和 4.7× 1 0 - 12 S- 1.
The granite mylonite of western foot of Lianyuan mountain is an important part of the dynamic metamorphic zone in ChangshoujieShuangpai strikeslip fault of Hunan province.On the basis of discussing microstructure feature of the mylonite, the ancient stress difference (σ_1-σ_3)and strain rate have been estimated by the way of dislocation density.The results are 80 Mpa and 4.7×10 -12 s -1 .
