They provide information on the provenance, the process of particle transport and temporal variation in the flux of source material. The Rb–Sr isotopic systematics of the core sediments show well-correlated pseudo isochrons. The pseudo isochrons reflect the mixing of two types of material, i.e., the Asian continental material with high       87   Rb   /      86   Sr    ratios (4.5–6.5) and high       87   Sr   /      86   Sr    ratios (0.723–0.727) and the volcanic material with low       87   Rb   /      86   Sr    ratios and low       87   Sr   /      86   Sr    ratios, from island–arc volcanics such as the Izu–Ogasawara–Mariana and the Japanese Islands and oceanic islands such as the Hawaiian Islands (0.0–2.0; 0.703–0.708). The clearness of the pseudo isochrons implies that the Rb–Sr isotopic composition of the weathering products derived from the Asian continental crust is extremely homogenized. The fine fraction (a few μm) with a high       87   Rb   /      86   Sr    ratio (5.0–6.5) is widely transported into the north Pacific by the middle-latitude westerlies and contributes largely to pelagic sediments. The coarser fraction with a lower       87   Rb   /      86   Sr    ratio
