| 摘 要： | 以奥斯陆国际地质大会修订的全球寒武系年代地层四分方案为依据, 通过对古生物化石、同位素年龄及与顶底和内部地层单位的接触关系等综合分析, 对西北地区16个地层区(地区)的寒武纪岩石地层单位进行了重新厘定。通过对比研究, 初步建立了西北地区寒武纪岩石地层划分方案(即4统10阶的年代地层框架), 为今后西北地区寒武纪地层研究工作提供了科学依据。

| Abstract: | Based on the comprehensive analysis of paleontology, isotopic ages and the contact relations between upper and inner lithostratigraphic units, and under the new global Cambrian framework with four series and ten ages, stratigraphic units of sixteen stratigraphic areas of northwestern China were redefined. By comparative study, the lithostratigraphy divison framework of northwest China was preliminarily established. This study would provide scientific evidence for stratigraphic studies in northwestern China. |
