生物地层学以物种的出现和消失为依据,其对比精度约为100万年;层序地层学以米兰凯维奇事件为导因,应用海泛面、叠置格局和可容空间作概念支柱,对比地层,其四、五级层序对比精度约在20万年左右。更高精度的地层对比,各方面都在探索。首次提出痕迹地层学概念,讨论了痕迹地层学的理论基础、研究方法、事件属性及事件间隔时限,旨在引起研究者对地层间断现象的注意,以利从地史时期生物行为中,获取较多的地层学信息,为高精度地层划分对比服务。
Biostratigraphy based on the emergence and disappearance of species, the contrast accuracy of about 1000000 years; sequence stratigraphy to the cause of the incident in MilanKevic, the application of the sea surface, stacking patterns and space as a conceptual pillar , Contrast stratigraphy, the fourth and fifth level sequence accuracy of about 200000 years. Stratospheric contrast, all aspects are explored. The concept of trace stratigraphy was proposed for the first time. The theoretical basis, research methods, event attributes and time interval of trace stratigraphy were discussed. The purpose was to attract researchers’ attention to the discontinuity of stratigraphy, Many stratigraphic information, high-precision stratigraphic comparison services.
