本文通过吉林大阳岔寒武系—奥陶系层型剖面野外地质考察,对其界线附近的沉积岩岩石学以及对区域地层对比有标志作用的海绿石进行了各种分析测试和综合研究,并对界线附近的沉积环境进行了有益的讨论。
In this paper, through the field geologic investigation of the Cambrian-Ordovician stratigraphic section in Dayangcha, Jilin Province, various analytical tests and comprehensive studies have been carried out on the sedimentary rock petrology near the boundary line and the glauconite, which has a marked effect on regional stratigraphic correlation. And discussed the sedimentary environment near the boundary line.
