Radiolarians from Sites 434, 435 and 436, northwest Pacific, Leg 56, Deep Sea Drilling Project.

Abstract

Of the rich and well-preserved Neogene radiolarians recovered during this cruise, this chapter discusses only those of biostratigraphic importance. It consists of a tabulation of occurrence-abundance, a radiolarian event list, and a range chart. In addition, it includes information suggesting certain phylogenetic relationships and a brief discussion of the correlation between the zones used in this report and those established in Japanese land sequences. Because of minor recovery and the poor state of preservation of Cretaceous radiolarians, only a few Cretaceous species are discussed.-from Author
