本文建立了造山阶段变质作用和重熔作用过程热方式研究的二维模式,该模式为:(1)基性/超基性岩浆在大陆地壳中的侵入;(2)流体通过一垂直渗透带的流动;(3)结合前文的合成流体—岩浆模式。问题的解决是利用计算机通过有限差分法完成的,从有关6km厚的似板状侵入体的第一个模式中,可以得出重熔带的宽度在顶岩石中达1km,在底部岩石中达2.5km。在侵入体上部变质带的总厚度能达到5～6km,其中包括重熔的岩石,在地壳内不规则高温的总持续时间为6～9Ma。对于流体的初始温度为700℃、流动
In this paper, a two-dimensional model of thermal modeling of metamorphism and remelting in the orogenic phase is established. The model is: (1) Invasion of basic / ultrabasic magmas in the continental crust; (2) (3) combined with the previous synthetic fluid-magmatic model. The problem was solved by finite difference method using a computer. From the first model of a plate-like invader with a thickness of 6 km, it can be concluded that the width of the remelt zone reached 1 km in the top rock and reached the bottom in the rock 2.5km. The total thickness of the metamorphic belt in the upper part of the intrusive body can reach 5 ~ 6km, including remelted rocks. The total duration of the irregular high temperature in the crust is 6 ~ 9Ma. The initial temperature for the fluid is 700 ° C, flowing
