为李四光教授所建立的长江峡东区的震旦系剖面,被看作南方各地同时期地层比较的标准。黄陵背斜东翼是所分各单位——“南沱砂岩”、“南沱冰碛层”、“陡山沱统”、“灯影灰岩”的典型地区,地层工作者来到峡区经常先察勘这里的剖面。考察过东翼剖面,可上溯一程去西翼或南翼探索其侧向变化。本文就笔者1961年冬,于西翼庙河—冀家湾区、东翼莲沱的沿江地带和南翼的秋千坪地区(见图1)所进行的一些观察及点滴认识,加以阐述。
The Sinian section of the Changjiang Gorge East, established by Professor Li Siguang, is regarded as a standard for stratigraphic comparisons over the same period in the south. The eastern wing of the Huangling anticline is a typical area of each unit - “Nantuo sandstone”, “Nantuo moraine”, “Doushantuo Tuo” and “light shadow limestone” Often first survey the section here. After examining the profile of the eastern wing, it can be traced back one course to the west or south to explore its lateral changes. This article on the author in the winter of 1961, in the West Wing Temple Temple - Jijiawan District, East Wing Lotus Hill and the south wing of the swing area (see Figure 1) carried out some observations and bit by bit understanding, to be elaborated.
