| 摘 要： | 永修—南昌剪切带中糜棱岩物质成分变异及体积变化分析结果表明,以Al2O3守恒为限制条件,该剪切带损失了9%的质量和体积,糜棱岩类Fe2O3明显带入,SiO2、K2O、MgO、P2O5、FeO、Na2O等组分明显带出。研究结果显示糜棱岩组分的得失和体积的变化主要发生在初糜棱岩化阶段。

| Abstract: | An analysis on the material component variation and volume change of the mylonite in the Yongxiu-Nanchang shear zone has revealed that under the constraint conditions of constant Al2O3,the shear zone has Lost9% mass and volume.The mylonite has an obvious gain in Fe2O3 and a loss in SiO2,K2O,MgO,P2O5,FeO and Na2O.Study has also revealed that the gain and loss in components and the volume change of the mylonite took place mainly in the incipient mylonization stage. |
