Accretionary complexes (AC) form at convergent plate margins by the subduction of oceanic plate underneath the continental plate (Fig. 2b.1). The oceanic plate is created at the mid-oceanic ridge, and moves to the trench while accumulating pelagic sediments. After arriving at the trench, where the pelagic sediments are covered by continent-derived clastic materials, the plate is subducted and part of the sediments accrete to the continental plate, producing fault stacking and several types of mèlanges (Fig. 2b.1). The characteristic AC succession re?ects the ocean plate stratigraphy (OPS) (Matsuda & Isozaki 1991) starting with basaltic basement covered by radiolarian ribbon chert, then siliceous mudstone and ?nally coarse clastic rocks.

The Geology of Japan
It has been 25 years since publication of the most recent English language summary of the geology of Japan. This book offers an up-to-date comprehensive guide for those interested both in the geology of the Japanese islands and geological processes of island arcs in general. It contains contributions from over 70 different eminent researchers in their fields and is divided into 12 main chapters:
Geological Evolution of Japan: an Overview;
Regional Tectonostratigraphy (consisting of seven separate sections giving full coverage both to the different geographic regions and different geological ages);
Ophiolites and Ultramafic Units;
Neogene-Quaternary Sedimentary Successions;
Deep Seismic Structure;
Coastal Geology and Oceanography;
Mineral and Hydrocarbon Resources;
Field Geotraverse, Geoparks and Geomuseums (with information on travelling by public transport to see some of the great geological sites of Japan).
Each chapter includes the unique contribution of an extensive aid to the written forms of geology-related names in Japanese.
