| 摘 要： | 目前的适山带变质作用PTt轨迹热模拟研究仍受变质作用程度由深度控制的传统观念的制约，其主要假定条件没有很好地反映造山带变质作用客观的和本质的特征，因而亦无法反映造山作用的真实过程和造山带变质作用的地质动因。造山带变质作用研究应朝着变质作用与构造变形作用、花岗岩化作用等多种地质作用综合研究、时间演化过程与三维空间变化特点有机结合、造山带变质作用时空演化特点与地幔深部地球动力学过程统一综合研究的方向发展。

| Abstract: | The present reseaching of forward modeling of orogenic metamorphism has been restrained bythe thought that metamorphic grade is function of depth.Its assumption didn't reflected the insitriccnaracteristics of orogenic metamorphism.The data from the reversing approches indicates that theuneven gushing of thermal and structural flow in orogenic belt results in progressive metamorphism,granitization and progressive deformation and development of thermal-structural-gneiss dome.It is important developing trend to combine temporal evolution and three-dimentional spetialvariation of progressive metamorphism,granitization and progressive deformation and construct aunified geodynamic system between orogenic metamorphism and the process of lithosphere movementunder the orogenic belt. |
