地层学要素也就是地层学基础,包括地层学的原则、概念、地层的划分、对比和命名等内容。有的研究者也把岩石地层、生物地层和年代地层看成地层学的三要素。 有许多地质文献涉及地层学要素问题。新近国际地科联地层委员会出版的《国际地层指南》是较全面系统阐述这方面内容的一个文件。我们认为,在现时提出一种世界范围的“指南”,为全世界地层研究规定某种类似“规范”性质的东西要求全世界统一采用,似乎 Stratigraphic elements are also the basis of stratigraphy, including the principles of stratigraphy, concepts, stratum division, contrast and naming and so on. Some researchers also consider rock strata, biostratigraphy and chronostratigraphy as three elements of stratigraphy. Many geological literature addresses the issue of stratigraphic elements. The International Stratigraphy Guide, recently published by the International Geoscience Commission, is a more complete and systematic account of this aspect. In our opinion, at the present time, a worldwide “guideline” is proposed to provide something similar to the “normative” nature of stratigraphic research throughout the world and requires that the world be uniformly adopted. It seems
