Abstract: | Abstract Main stages of radiolarian taxonomic evolution in the Pacific rim of Russia are discussed. The diversity and distribution of radiolarian assemblages displayed in the studied sections and their geological and tectonic setting have implications regarding paleoecological and paleo-oceanographic conditions as well as paleotectonic reconstructions. Radiolarian events show the close relationship with the tectonic rearrangements in the Pacific and in North America. The attempt to analyze paleo-oceanological aspects and major factors affecting radiolarian events is presented. |
