沉积盆地动力学研究的新进展

沉积盆地动力学研究在９０年代向多维、多角度、多种研究手段相结合的方向迈进。多维体现在盆地研究延拓至岩石圈层次、上部脆性变形与下部韧性变形相结合，造山带研究与盆地研究相结合，流变学、应力状态等随时间变化影响盆地动力学演化研究方面；同时，构造时间非线性因素也制约着盆地动力学历程。多角度体现在对制约盆地演化的热、应力与重力因素的综合研究，对盆地形成的热作用研究进一步加强，对岩石圈应力的时空演化与岩石圈形变对盆地动力学的影响有了深刻的认识，对重力的成盆作用有了新的探讨。多种研究手段如数值模拟、构造物理模拟实验以及二者的结合等已用来研究沉积盆地动力学演化。

ADVANCES IN STUDIES OF THE DYNAMICS OF SEDIMENTARY BASINS

In 1990s studies of sedimentarv basin dvnamics advance in multi-dimentionaland multi-direction research and in application of many new technological methods.Themulti- dimensional research lies in the basin studies integrated with the lithospheric stud-ies,the upper brittle and the lower ductile deformation,the orogenic belts and basins,andthe dynamic evolution of basins controlled by rheological changing and changing of thestress,etc.in time and by structural and transient non- linear elements in lithospheric dy-namics. The multi- direction research is shown in the comprehensive studies of factors suchas thermal,stress and gravity,etc.which play a great role in basin formation,in the un-derstanding of basin dynamics influenced by the space and transient evolution of the litho-spheric stress and deformation,and in the discussiori of basins originated from gravity. Many new methods such as mathematical modeling and analogue modeling have been usedin the research of dynamic evolution of sedimentary basins.
