Abstract

Remains of benthic cyanobacterial communities formed under shallow-water littoral conditions of were found in the Upper Vendian Zavkhan cyano-algo-bacterial association of the upper terrigenous-carbonate section of the Tsagaan-Olom Formation (<632 ± 14 Ma) of the Zavkhan structural-formational zone in Western Mongolia. Filamentous cyanobacteria of the genus Siphonophycus were the main builders of mats. Benthic cyanobacterial communities mark the shallow-water facies of the regressive stage of development of the vast postglacial Vendian–Cambrian Zavkhan paleobasin in Western Mongolia.

蒙古西部晚文德纪Zavkhan协会蓝藻群落与文德-寒武纪沉积物形成的古环境

摘要

在 Zavkhan 构造的 Tsagaan-Olom 组 (<632 ± 14 Ma) 的上陆源碳酸盐部分的上 Vendian Zavkhan 氰基-藻类细菌群落中发现了在浅水沿岸条件下形成的底栖蓝藻群落残骸-蒙古西部的构造带。Siphonophycus属的丝状蓝细菌是垫子的主要建造者。底栖蓝藻群落标志着蒙古西部广阔的冰后文迪-寒武纪扎夫汗古盆地退行发展阶段的浅水相。
