运用岩浆动力学原理探讨了西准噶尔东部碱性花岗岩浆侵位的驱动力、上升通道、通道最小临界宽度和定位过程。指出:碱性花岗岩体是由其岩浆主要在区域性挤压应力作用下,沿深大断裂以最小临界宽度1.33~301m的脉状上升,并在地壳浅部发生气球膨胀和岩墙扩张.定位于与区内深大断裂有关的次级张性裂隙发育部位后形成的。
Using the principle of magma dynamics, the driving force of ascending emplacement of granite magma in the eastern part of West Junggar, the minimum critical width and the process of ascending channel and channel are discussed. It is pointed out that the alkaline granite body is mainly composed of magma whose regional magmatic compressive stress increases along the deep fault with a vein with the minimum critical width of 1.33-301m and causes balloon expansion and dilatancy in shallow crust . It is formed after the development of the secondary tensile fracture related to deep faults in the area.
