论中国陆相盆地地层层序体系域的可四分性及其优势

由于受海相地层层序划分的影响,特别是考虑到与海相地层层序分的一致性,导致陆地层层序内体系域的划分方案长期争论不休。在前人研究的基础上,文章通过对沉积旋回和陆相盆地层序充填过程的分析,以及对中国多个陆相盆地地层层序实际沉积序及其划分方案的研究,论述了陆相盆地地层层序四分法的合理性,并且认为四分法更具有包容性和完整性。建议采用低水位体系域,水进体系域,高水位体系域和水退系域四个体系域对陆相层序进行划分。

Discussio on "one divides into four" property of system domain for stratigraphic sequence of terrestrial basins of China and its advantages

Influenced by the division for marine stratigraphic sequence, especially considering the division consistency between the marine and terrestrial stratigraphic sequence, debate on the system domain division schemes of terrestrial sequence is endless for a long time. Based on the researches of the predecessors, sedimentary cycle and the sequence packing processes of the terrestrial basins are analyzed, and real sedimentary sequence and its division scheme in various terrestrial basins of China are studied. Then the rationality of "one divides into four" method for stratigraphic sequence of terrestrial basins is discussed in this paper. It is considered that this method has more containment and more completeness. It is suggested that the stratigraphic sequence of terrestrial basins of China should be divided into four system domains as lowstand system domain, transgressive system domain, highstand system domain and regressive system domain.
