| 摘 要： | 华北陆块东南缘凤台组归属于震旦系或寒武系尚无定论,影响了对华北陆块震旦纪与寒武纪转折时期的古构造、古地理和古生物的重大质变事件的探讨。本文根据下震旦统顶部与凤台组之间裂离不整合的发现及其意义的讨论,以及凤台组夹层粉砂质泥岩620Ma的Pb-Pb等时线年龄,基本厘定出凤台组时代为晚震旦世。

| Abstract: | There was an argument about age of the Fengtai Formation being Sinian or Cambrian. Based on the discovery of breakup uncomformity between the Lower Sinian Sidingshan Formation and the Fengtai Formation, the field features and geochemical evidence of the unconformity, and the Pb-Pb isochronal dating of silt mudstone interbeds from the Fengtai Formation being 620 Ma, the paper thought that the Fengtai Formation should be deposits of Late Sinian. This result might stimulate the study of paleostructure, paleogeography and paleontology in the transitional period between the Sinian and Cambrian in the North China Block. |
