| 摘 要： | 运用二维有限元方法模拟了在盆地演化过程中，岩浆的侵入对盆地热演化的影响．针对岩浆侵入过程所体现的特点．在有限元计算中采用了变网格技术．模拟表明，宽约为３ｋｍ左右的岩浆体热影响范围约为５ｋｍ以内的岩石，在侵入后０．５百万年左右的时间内影响最大，持续时间约为３百万年．

| Abstract: | Using two dimensional finite element method,we modeled the influence on the thermal evolution of a basin after magma intrusion.According to the features appearing in the magma intrusion we took advantage of changing the finite element mesh.The result indicated that when the dike is about 3 km wide the range of influence is 5 km or so.During the 0 5 Ma after intruding the magma have the greatest influence on the surrounding rocks and the influence time last 3 Ma. |
