Abstract

<p>Progress in Neogene radiolarian biostratigraphy in Japan and the North Pacific region during the last two decades is characterized by (1) the direct correlation between the radiolarian biostratigraphy and the magnetostratigraphy, which has now been extended back to the Middle Miocene using deepsea cores, (2) advances in regional Neogene radiolarian biostratigraphy from the Northwest Pacific, the California margin, and the Japan Sea, and (3) application of the revised zonations to correlate onshore Neogene sections. These results have been supported by the reinvestigation of type-species described by earlier studies in the 19th to earliest 20th century, revision of taxonomic systems from lower to higher taxa, and researches for new biostratigraphic index fossils. Great advances have also been made in Quaternary radiolarian biostratigraphy in the nearshore seas surrounding the Japanese islands, proposing new radiolarian zones for the Kuroshio and Oyashio regions and the Japan Sea.</p>
