| 摘 要： | 前言河南省横跨华北地台南缘和秦岭褶皱系东端。这里的寒武系发育良好,分布广泛,且有着不同类型的沉积相和古生物群。区内寒武系主要分布于华北区(豫西、豫北地区)和东秦岭南麓(淅川地区)。总体而言,华北区的寒武系与山东、河北等地类似,但在岩性特征和生物面貌上也稍有差别,淅川地区的寒武系南北分异显著:淅川北部地区与峡东地区酷似;淅川南部地区则与湘西、黔东及祁连山等地相似。区内寒武系划分见表1。 |

| Abstract: | Henan Province is situated across the southern margin of the North China platform and the eastern end of the Qinling fold system, where the Cambrian strata comprising various types of sedimentary facies and a variety of biotas are well developed and widely distributed. Based on the analysis of the fossil communities, five Cambrian biofacies in Henan Province have been established, i.e. littoral tidal flat biofacies (BF1), restricted shallow-water biofacies (BF2), open shallow-water biofacies (BF3), deeper-water shelf biofacies (BF4) and stagnant basin biofacies (BF5). Their characteristics are shown in Fig. 1. The study of the Cambrian biofacies is of great importance to the recognition of sedimentary facies, to the division of the Cambrian biogeographic provinces and to the reconstruction of the Cambrian palaeogeography. |
