沉积盆地的动力学分析──盆地研究领域的主要趋向

GEODYNAMICS OF SEDIMENTARY BASINS── THE MAIN TREND OF BASIN RESEARCH

沉积盆地的动力学正在成为盆地研究领域的主要趋向，并将成为跨世纪的固体地球科学研究规划中的重要组成部分。其目的在于认识盆地的成因，揭示其全部演化历史中的动力学过程，并探求来自地球系统的内在驱动力。这将需要定量地分析反映动力过程的参数，阐明各种控制因素的联合、复合作用及演化中的过程序列。了解盆地演化与发生在深部，包括地壳和岩石圈以下的物质状态和过程之间的关系以及板块相互作用所造成的成盆区应力场，这将是盆地动力学理论研究所必须面对的问题。定量动力学模拟技术的新进展已表明其为这一领域研究不可缺少的支柱。层序和事件地层学、构造－地层分析和高精度定年技术的结合提供了完整的研究盆地充填动力学的方法。盆地流体研究正在成为这一领域的热点。已取得的成就源于多学科联合研究和新技术的使用，坚持这一科学界的共识将是继续取得新突破的保证。

The study of basin geodynamics is becoming a main trend of the basin research.The goal and scope of this subject are to understand the mechanism of basin formation,to reveal the dynamic processes during basin evolution and the driving forces originated inside the earth system. The principal work is to study the geodynamic parameters reflecting the deep processes occurring beneath the crust and lithosphere and to investigate the stress field affected by the interaction of plates. Quantitative dynamic modeling is a very efficient means for this study. The combination studies of sequence and event stratigraphy,tectono-stratigraphic analysis and high-resolution timing technique may offer an integrated approach for the study of basin filling dynamics. Fluid flow and its driving system in sedi-mentary basins have grown to be a highly prior research field of the Earth sciences. Multi-disciplinary study and team work are critical for the new breakthrough in the study of basin geodynamics.
