在华北地块中-上元古界长城系高于庄组一、二段和蓟县系洪水庄组、铁岭组以及青白口系下马岭组中发现上升流沉积.总结了该区上升流沉积的基本特征.通过对上升流沉积岩相的分析,将其划分为燧石条带、叠层石、黑色页岩、硅质泥岩和硅质岩5种上升流岩相类型.根据不同上升流沉积岩相的组合规律.又划分出两种岩相组合类型,即潮下高能带上升流岩相组合和潮下低能带上升流岩相组合,进而对研究区沉积体系组合的形成机理进行了探讨,并建立了相应的上升流相模式.

The Basic characteristics of the upwelling sediment are summarized,which were discovered in the first and second member of the Gaoyuzhuang Formation, Hongshuizhuang Formation,Tieling Formation and Xiamaling Formation in North China Block. According to the analyses of upwelling sedimentary facies.it is considered that upwelling lithofacies can be classified into five types as chert bands, stromatolites, black shales, siliceous mudstones and siliceous rocks. Based on the combination law of different upwelling lithofacies, the upwelling lithofacies associations in infra-tidal high energy belt and infra-tidal lower energy belt are recognized. The formation mechanism of sedimentary system association and the upwelling facies model are analyzed.
