摘要
Li等(2020)建立了西藏南部三叠纪—古近纪综合生物地层表。该表系统梳理并总结了藏南地区近年来在地层学和古生物学方面的新材料、新进展,以当前国际年代地层表的框架为标准,包含了各纪主要标准化石门类序列。另外,表中还新建了一些过去没有或研究程度差的门类的序列,如放射虫和孢粉等,因此具有很好的应用性和参考性。本文对此表做简要介绍,并对区内有关岩石地层的划分、对比和时代争议予以必要的梳理和澄清。
Li et al.(2020) established a new integrated biostratigraphic chart for the Triassic-Paleogene strata in southern Xizang(Tibet), China. The work systematically summarized the new material and advances in stratigraphy and palaeontology obtained in the recent decades. The chart took the stratigraphic framework in the current international geological time scale as the standard to correlate by focusing on main standard fossils of each period. In addition, some other useful fossils that had been poorly studied previously were progressed to a sequence, such as radioralian and sporopollen, making the new biostratigraphic framework fairly applicable and referable. This paper gives a brief introduction to this chart and, moreover, makes some essential comments on some lithostratigraphic issues in southern Xizang.
