The correlation of erosion and deposition as a basis for the stratigraphic (division) of continental basins
-
摘要: 陆相盆地由于纵横向岩性突变和缺乏化石,导致地层划分往往十分混乱。陆相红盆的沉积始终离不开基底母岩的供给。笔者通过剥蚀与沉积的相关性研究实例,来说明其在陆相盆地划分和研究中的实际作用和意义。把盆外母岩的风化剥蚀与盆内堆积的相关性关系研究紧密结合起来,可以极大地提高陆相地层划分的分辨率;同时也有助于加强盆地构造活动的研究。Abstract: The sharp vertical and horizontal lithologic changes and the lacking of fossils often cause the stratigraphic division of continental basins to be much debated. The deposition in continental basins is always dependent upon the delivery of the basement parent rocks. The correlation of erosion and deposition is thus believed to be very significant in the stratigraphic division of continental basins. The combination of extrabasinal weathering and erosion of parent rocks and intrabasinal deposition may improve the resolution of continental stratigraphic (division), and the understanding of tectonism in the basins.
