本文对目前存在的裂谷盆地的两种理论模型进行了模拟,并通过其与实际盆地的观测资料的拟合,来确定盆地的形成机制和演化历史,得到有关盆地演化过程中诸如伸展量、构造沉降量、岩脉侵入量及古热流变化等参数。
Two kinds of theoretical geodynamic models (the uniform extension model and thenon-uniform extension model)of extensional basins were used to simulate the observed tectonic subsidence of the Songliao Basin to discuss the mechanism of extensional basins. Byfitting it with actual measured data,he genetic mechanism and evolution history of thebasin can be further recognized.Especially,the quantitive parameters of basin evolutionprocess such as extension quantity,tectonic subsidence,paleo-heat-flow,paleotemperatureand vein intrusive amount can be calculated.
