Yanguanian strata of Lower Carboniferous System are well exposedwith rather obvious variation in sedimentary facies, which are classifiedby the author as carbonate platform facies, fore-slope facies and argillo-siliceous rock facies. Within the platform facies district, warm shallow water and prosperoussea living creatures were ever favorable to the sedimentation of carbo-nates, forming argillic limestone, psammitic limestone, bioclastic lime- stone, micritic limestone and dolomite, together with tempestites...

Yanguanian strata of Lower Carboniferous System are well exposedwith rather obvious variation in sedimentary facies, which are classifiedby the author as carbonate platform facies, fore-slope facies and argillo-siliceous rock facies. Within the platform facies district, warm shallow water and prosperoussea living creatures were ever favorable to the sedimentation of carbo-nates, forming argillic limestone, psammitic limestone, bioclastic lime- stone, micritic limestone and dolomite, together with tempestites or stormdeposits. Massive bedding, graded bedding, middle-size cross bedding,laminated bedding, hummocky cross-bedding etc. are commonly observed.The total thicknesses vary between 300 and 500 metres. In tke foreslope sedimentary facies district, with slightly deepwater, were developed micritic psammitic limestone, micritic limestoneand laminated limestone, slump brecciated limestone formed by debrisflow and turbent current with synsedimentary folds and faults, wedge-shaped bedding, cutting structure, graded bedding and laminated struc-tures. We can see both benthos and plankton fossils and can observe bothexotic fossils from shallow water and original fossils formed in deepwater. In the mold facies district, deep water was unfavorable to benthosesbut planktons, forming mudstone, shales and siliceous rocks with 100to 300 metres thick. Horizontal lamination was well developed in theserocks. There are two sedimentary models: (1) The fault-controlled stiff-cliff sedimentary model. Sedimentation is greatly influenced by the Caledo-nian basement faults. There is obvious inheritance between the facieswhich consist of carbonate platform facies and argillo-siliceous rockmold facies with undeveloped slope facies. There are great changes inlithology, lithography and the thickness of sedimentary rocks between thedifferent facies which were connected with each other by fault-cliffs;(2) The low-angle slope sedimentary model is uncontrolled by basementfaults and composed of platform facies, foreslope facies and mold faciesamong which lithology, lithography and thickness vary gradually. The discovery of Nanbiancun international prospective stratigraphicsection-one of the typical foreslope facies reveals the mystery of thepuzzle of the change between platform facies and mold facies, whichwill be pretty significant for sedimentologists to identify and comparethe sedimentary boundary between Devonian and Carboniferous systems.

At present,the age of storm deposits reported in China may be traced back to late proterozoic. This paper, however, presents evidence of the presence of storm deposits in the middle Proterozoic Wumishan Formation in the Jixian area.The storm deposits are mainly developed in the proximal shallow-sea basin facies and gentle slope zone below the normal wave base. A distinctive feature of the storm deposits of this formation is that they have a close genetic relation with gravity flow and turbidity current activity....

目前我国已报导的风暴沉积时代可追溯到晚元古代。本文进一步提出了蓟县地区中元古界雾迷山组中存在着风暴沉积的证据。雾迷山组风暴沉积主要发育在正常浪基面之下的近源浅海盆地相及缓斜坡带之上。该组风暴沉积的一个显著特征是,与重力流或浊流活动有着密切的成因联系,其剖面结构多属不完整型及复合型。

本文论述了对湘西黔东地区早、中寒武世的碳酸盐岩和陆源碎屑沉积的分析研究结果,着重探讨了控制该区陆表海沉积层序的各种动力因素。在研究区内,4种垂向层序均具有向上变浅的旋回性。早寒武世晚期的藻丘缓斜坡与中寒武世的鲕粒陡斜坡上的沉积动力学特征为:滨岸正常波浪潮汐流,滨岸及内陆棚的风暴营力,垂直于古岸线的大规模地滑和重力流,沿古岸线及斜坡的等深流。沉积小旋回的成因系构造断块的脉动,而盆地边缘的海退序列则由板块相对扩张、海平面变动及碳酸盐岩自身成长所控制。
