Fig. 2From: Cyclostratigraphy of the Late Miocene to Pliocene sediments at IODP sites U1425 and U1430 in the Japan Sea and paleoceanographic implicationsAge-depth plot of sites U1425 and U1430. Biostratigraphic age control points are shown as symbols. Symbols with parentheses are biostratigraphic datums that are considered as less reliable. Detail explanation is given in the text. 405- and 100-kyr correlation points are also shown (red and blue circles). a U1425, b U1430Back to article page
