沉积盆地构造热演化模拟的研究进展

沉积盆地构造热演化模拟建立在盆地成因的地质地球物理模型基础之上,其中包括运动学模型、运动学—流变学模型和动力学模型。运动学模型在预测盆地热流演化方面具有优势,但在预测构造沉降等几何形态方面存在一定的缺陷;运动学—流变学模型的优势在于构造演化模拟,在热演化方面类似于运动学模型;动力学模型蕴含着潜在的巨大优势,只是目前还存在一些阻碍因素。构造热演化正演模型的进一步完善及正、反演模型的匹配将是未来构造热演化模拟的发展趋势。

ADVANCE IN TECTONO-THERMAL MODELLING OF SEDIMENTARY BASINS

Tectono thermal modeling is based on the geological geophysical models of basin formation, which include kinematic model, kinematic rheological model and dynamic model. Kinematic models have predominance in predicting heat flow but weakness in simulating basin geometry; Kinematic rheological models are adept in tectonic modeling, but identical with kinematic models in heat flow prediction; Dynamic models contain latent advantages and also some obstacles in tectono thermal modeling. Future study should put emphasis on further improvement of tectono thermal models and its matching with reverse models.
