“中国地层指南”颁发以来,在新指南的推动下,在地层学研究领域内,在生物地层和时间地层单位的划分和对比方面,在建立地层层型方面都取得了显著的进步,井巳经或者正在接近达到世界先进水平。然而这个指南在促进岩石地层研究的深入方面却并不能令人润意。特别是其中有关岩石地层 Since the issuance of the Guide to Stratigraphy in China, with the guidance of the new guidelines, significant progress has been made in establishing stratigraphic stratigraphy in the study of stratigraphy and in the division and comparison of biostratigraphy and time stratigraphic units, After or near the world advanced level.
