【摘要】 延边地区二叠系 70余年来的研究历史 ,是一部争论—前进—再争论—再前进的地层研究史。迄今虽然尚未取得共识 ,但运用“现代地层”和“大陆边缘”理论观点 ,分析已经取得的丰富的实际资料 ,表明现在在空间上紧接相邻的某些岩石地层 ,在二叠纪时是分属龙岗 (和龙 )地块北部陆缘活动带、兴凯地块西部陆缘活动带、佳木斯地块南部陆缘活动带不同空间的沉积产物。按照岩石地层单位的定义 ,应首先划分不同陆缘的岩石地层序列 ,而后通过分隔陆缘的相对的深水盆地相的岩石地层序列为桥梁去认识各陆缘带间岩石地层序列的相互侧向关系。但在造山带中 ,相对的深水盆地相的岩石地层 ,常因消减作用难见其踪迹 ,此时 ,仅能通过年代地层的对比判断各陆缘带岩石地层序列可能存在的侧向关系。为此 ,本文在拟建各陆缘带岩石地层序列的基础上 ,探讨了其年代地层关系 ,期求为解决本区二叠纪岩石地层划分的长期争议 ,提供一个新的统一划分方案 ,供研讨和实践检验之。

【Abstract】 The past 70 year history on research of the Permian strata in the Yanbian area shows that the argument is still continuing. Up to now the indentical views have not reached. On the basis of the plantiful and practical data and by the theory of the “present-day strata” and “the continental margin”, it is showed that some strata respctively belong to Longgang (Helong) land mass, northern epicontinental mobile belt, Xingkai land mass, western epicontinental mobile belt, Jiamusi land mass, southern epicontinental mobile belt in the Permian. According to the difinition of the rock-stratigraphic unit, firstly, should divide the rock-stratigraphic sequence to different continental margins, and then, distinguish mutual relation of the rock-stratigraphic sequence in the pericontinental zone.\;The lithostratigraphic zone of the relative deep-water basin facies is found very little due to the subduction, so, the possible existing sidewise relation in space can be determined only by chronostratigraphic correlation. For this reason, a continental rock-stratigraphic sequence is set up. This paper discusses chronostratigraphic relationship, so, to solve the long-term contention of the Permian rock-stratigraphic division, meanwhile, proposes a new, unified, division standard for further research.
