我国层序地层学研究的发展趋势

Trend of development of sequence stratigraphy in China

目前,定性的地质描述、宏观地质现象的追索、测井及地震地层的对比分析是层序地层学研究的主要方法,但定量化分析和微观测试的应用也已成为精细、准确、高分辨率层序地层研究的更高要求。因此,21世纪的层序地层学必将向微观、定量和高精度等三个方向发展。微观方向主要包括成岩层序地层、胶结物层序地层和同位素层序地层等;定量方向主要包括数学模型、计算机模拟技术和实验模拟等;高精度方向主要包括高分辨率层序地层学和高频层序地层学。同时,遗迹学、高分辨和高精度地震、高精度的测井技术、古地磁、X—衍射、计算机和通讯技术等新技术、新方法为现代层序地层学的研究和应用提供了保证,推动层序地层研究向更深和更高层次发展。

Qualitative geologic description, tracing of macroscopic geologic phenomena and correlation of logging and seismic stratigraphy are the main study methods of sequence stratigraphy at present Quantitative analysis and microscopic test have been becoming the major study methods of fine, accurate and high resolution sequence stratigraphy. Therefore, sequence stratigraphy will surely develop in the directions of microscope, quantification and high accuracy in the 21 century. Microscopic study mainly includes diagenetic sequence stratigraphy, cement sequence stratigraphy and isotopic sequence stratigraphy. Qualitative study mainly includes mathematical modeling, computer simulation and experimental modeling. High accuracy study mainly includes high - resolution sequence stratigraphy and high frequency sequence stratigraphy. In addition, several new methods and technologies, such as ichnology, high resolution and high accuracy seismic, high resolution logging, palaeomagnetism, X-diffraction,computer and communication, have provided support to research and application of modern sequence stratigraphy and promote its development.
