| 摘 要： | 青海省纳日宗地区古生代地层的调查与研究始于上世纪五十年代,虽然前人对区域地层多重划分对比进行了厘定,但其主要是基于七十年代完成的1:20万区域地质调查。笔者在纳日宗地区1:5万地质填图中划分出6个晚古生代地层单元,查明受宗务隆山-青海南山断裂带控制,填图区可划分出南祁连山区和宗务隆山区两个古生代地层分区。通过对比两个地层分区的晚古生代地层,讨论不同地层的叠置关系,南祁连山地层分区晚古生界为不整合于上元古界之上的早-中二叠世海相-海陆过渡相地层,而宗务隆山地层分区基底不清,发育早石炭世晚期-早二叠世晚期海相地层。

| Abstract: | The investigation and study of Paleozoic strata in Narizong area of Qinghai Province began in the 1950s. Although previous studies have determined the regional stratigraphic multiple division, it was mainly based on the 1:200,000 regional geological survey completed in the 1970s. The author divided 6 late Paleozoic stratigraphic units in the 1:50,000 geological mapping of Narizong area, and discovered that controlled by longshan - nanshan fault zone, the mapping area can be divided into two Paleozoic strata zones: the south Qilian Mountains and the Zongqulong Mountains. By comparing the late Paleozoic strata in two strata zones, the superposition relationship of different strata was discussed: the late Paleozoic strata in the stratigraphic division of the south Qilian Mountains were the early - middle Permian marine - continental transitional strata unconformably above the upper Proterozoic, whereas, the base of the stratigraphic division in Zongwulongshan Mountains was not clear, which was marine strata from late early Carboniferous to late early Permian. |
