西伯利亚地台早寒武世钙藻的发育特征(英文)

PECULIARITIES IN THE DEVELOPMENT OF EARLY CAMBRIAN CALCAREOUS ALGAE ON THE SIBERIAN PLATFORM

西伯利亚地台的新元古代到早寒武世间的钙藻化石特别丰富 ,为研究钙藻化石的发育历史提供了模式。在几次演化事件背景下记录了演化的两次转折 ,其中一个是藻类的普遍钙化 ,还有一个是 Botom ian晚期到 Toyonian早期之间在西伯利亚地台缺失钙藻化石记录 ,而在其它地区包括西伯利亚地台的边缘 ( Altay- Sayan地区 ) 。

The Siberian Platform is the model for studies of a history of development of calcareous algae that appeared in abundance at the transition from the Late Proterozoic to the Early Cambrian. Against the background of several events, two crises were recorded in their evolution, one of which was the fact of algae calcification; in the Late Botomian- Early Toyonian time they were not recorded on the platform, whereas in other areas including the periphery of the platform (Altry-Sayan region) this time is characterized by maximum in calcareous algae.
