河南省三叠系均为陆相地层,华北区及北(东)秦岭区均有分布,华北区三叠系层序基本齐全;北秦岭区仅具三叠系上统。三叠系的分布及沉积特征明显受印支期构造控制,並强烈影响东西邻区。其原因拟为华北板块与扬子板块在印支期发生碰撞所致。
The Triassic strata in Henan Province are all continental facies. Both North China and North (East) Qinling are distributed. The Triassic sequences in North China are basically complete; the North Qinling is only Triassic. Triassic distribution and depositional features are clearly controlled by the Indosinian tectonics and strongly affect the eastern and western neighbors. The reason for the North China plate and the plate in the Indosinian collision occurred due to.
