摘要
沉积盆地是地球系统的浅层组成部分,是壳-幔、岩石圈-软流圈两级圈层相互作用的浅部表现形式。沉积盆地分析不仅可以揭示不同类型化石能源、沉积型层控矿产、砂岩型铀矿等资源的分布规律,为矿产勘探提供直接依据,而且可以为大地构造演化过程、重大构造事件、全球环境变迁及气候演变提供丰富资料和详细证据。当代盆地分析不断从单一沉积学分析拓展到综合分析,从静态要素分析拓展到过程和动力机制分析。盆地动力学研究内容包括3部分,即以沉积学分析为主的盆地充填动力学、以构造地质学分析为主的盆地形成演化动力学和多学科交叉的盆地流体动力学研究。近10多年来,盆地动力学研究在深水沉积学、高精度层序地层学、源-汇系统、源区剥蚀过程及其深部响应、大陆边缘盆地动力学及盆地流体动力学等方面取得了长足的进展。
Depositional basin is taken as a main component in shallow part of earth system resulted in the interaction of crust and mantle, lithosphere and asthenosphere. Analysis of depositional basin not only reveals distribution of fossil resources, depositional-dominated ores, clastic aranium deposits, being directly helpful for resource exploration, but also provides a plentiful information and evidence for studying on regional tectonic evolution, important tectonic events, global environment changes. Development of basin analysis shows clear transition from simple analysis on sedimentology to integrated analysis of multidisciplinary, and from static elements analysis to process and dynamic analysis. Research topics of basin dynamics include basin fill, basin formation and evolution, and basin fluids analysis. Recently, great achievements have been made in deepwater sedimentology, high-resolution sequence stratigraphic analysis, source to sink system, relationship between erosion variation and deep process in erosion area, continental margin dynamics, and basin fluid analysis.
