Abstract

Using a radiolarian method, correlation of stages and substages of the Middle Mesozoic submarine volcanic-siliceous sequences was carried out for the vast territory of Eastern Asia for the first time. The correlation of fragmented outcrops of genetically various siliceous-terrigenous-volcanic rocks showed a broad lateral distribution of sediments from the Norian to Hauterivian stages inclusive within the studied area. This work, based on a combination of paleontological, structural-tectonic, and lithological-petrological methods in contrast to the terrane approach, has demonstrated the possibility of age and facial characteristics of isolated outcrops of the Middle Mesozoic submarine rocks for the huge territory of Eastern Asia.
