摘要
江西九岭花岗岩体南缘不同时期的花岗岩中,发育有规模不等的韧性剪切带,剪切带变形岩石主要类型为具S—C型组构的花岗质糜棱岩。剪切带岩石变形始于早古生代(410.79Ma),晚古生代(374.8Ma)是剪切带的主要变形时期,中生代(119.6Ma)至新生代仍有小规模的韧性变形。岩石的变形温度为605~663℃。
There ar ductile zones of different scales in which the deformation rocks are granitic mylonites with S-C textures at the southern margin of granite mass,Jiuling,Jiangxi.The deformation of shear zone started in Lower Palaeozoic Era (410 79Ma).The major deformational time of shear zone was Upper Palaeozoic Era (374 8Ma).There were small-scale ductile deformations in Mesozoic Era and Cenozoic Era.The deformational temperatures were 605~663℃.
