Abstract:
Volcanogenic sediments were obtained from Site 584, located on the midslope of the Japan Trench. Occurrences of volcanic ash in the diatomaceous mudstones increase within sediments dated 6-3 Ma. The frequency pattern and the sediment accumulation rate obtained at Site 584 are similar to those of Site 440 and to those of Sites 438 and 439, located on the upper slope basin. Explosive volcanism increased during the Pliocene and late Miocene in relation to the intrusion of Tertiary granites and uplift of the Tohoku Arc (northeastern Japan Arc). Hygromagmaphile element concentration shows that the glass does not belong to a unique series, and a comparison with Nankai Trough data distinguishes at least two different evolutionary lines.
