热泉地区岩浆侵入过程的热演化特征

The Characteristic of Thermal Evolution of Magma Intrusion in Hot Spring Area

参照腾冲－梁河地热系统的特点及岩浆活动的一般特征，应用二维有限单元法定量模拟了热泉地区岩浆侵入的热演化过程．计算中，采用等效比热方法处理潜热释放问题，同时建立了大气降水对热液循环的补给模型．计算结果表明：半宽度为０．

According to the parameters of Tengchong Lianghe geothermal field and the feature of magma active,we have calculated consequences of magma remaining thermal at got sprint area.In two dimensional thermal modeling,we use a method of equivalent heat capacity to handle the latent heat effect and build a model of hydrothermal circulation system.The result shows that the thermal effect of magma is about 4 kilometers from magma intrusion in our study.
