首次通过小秦岭变质核杂岩同变形变质过程形成的绿帘石成分环带之间的组份变化 ,使用Gibbs方法研究了绿帘石生长期的P_T路径 .这些P_T路径反映了该变质核杂岩经历了深部地壳的近等压降温 ,通过迅速减压升温伸展隆升到中部地壳 ,继之在中部地壳近等压降温的热动力学过程 .在这一隆升过程中 ,深部岩浆侵位和上隆是最主要的因素之一 For the first time, through the Gibbs method, the P_T path during the epidote of epidote was studied through the compositional changes of epidote from epithermal metamorphic processes in the Xiaoqinling metamorphic core complex.These P_T paths reflect the metamorphic core complex Experienced near-pressure cooling in the deep crust, expanding rapidly to the central crust by rapid depressurization and warming, followed by thermodynamics of near-pressure cooling in the central crust. During this uplift, the deep magma emplacement and Uplift is one of the most important factors
