摘要
运用地震地层学方法，将南海西部中建南盆地新生界划分为6个地震层序，并进行了地震相－沉积相分析，推断解释了14种沉积相，论述了不同地质时期各沉积相的平面分布特征，分析了新生代盆地沉积环境的演化和各沉积体系在盆地发展过程中的变迁，进而展示了中建南盆地由陆相湖盆向陆缘海盆的演化。
Based on seismic stratigraphy interpretation, this paper has identified six seismic sequences, made a correlation between seismic and sedimentary facies, interpreted 14 sedimentary facies and discussed areal distribution of each sedimentary facies during different geologic times for Cenozoic sediments in Zhongjiannan Basin, South China Sea. The evolution of Cenozoic sedimentary environment and changes of each sedimentary system during development of the Basin are also discussed, indicating a gradual transition of Zhongjiannan Basin from a lacustrine basin to a continental margin marine basin.
