本文以基本层序、标志层在赣西北古生界以及三叠纪地层应用为例,阐述了这两种方法各自功能以及相互渗透、相互结合的作用。论述了这两种方法在1:50000区调中的作用以及重要性,强调了在加强层序地层学研究同时,应注意与一些具高分辨率的地层学方法结合起来,这是把区调层序地层学工作做得更好的保证。 In this paper, taking the basic sequence, the application of the marker layer in the Paleozoic and the Triassic strata in the northwestern Jiangxi Province as an example, the functions of the two methods as well as their mutual penetration and mutual integration are expounded. The function and importance of these two methods in the 1: 50000 zone are discussed. It is emphasized that in the process of strengthening the sequence stratigraphy, attention should be paid to combining with some high-resolution stratigraphic methods. Sequence stratigraphy work done better guarantee.
