Pre-Cenozoic rocks of the Japanese islands are largely composed of latest Palaeozoic to Cretaceous accretionary complexes and Cretaceous granitic intrusives. Exposures of older rocks are restricted to a limited number of narrow terranes, notably the Hida, Oeyama and Hida Gaien belts (Inner Zone of SW Japan), the Kurosegawa Belt (Outer Zone of SW Japan) and the South Kitakami Belt (NE Japan). In these belts, early Palaeozoic basement rocks are typically overlain by a cover of middle Palaeozoic to Mesozoic shelf facies strata. This chapter describes these basement inliers and their cover, grouping them under four subheadings: Hida, Oeyama, Hida Gaien and South Kitakami/Kurosegawa belts. Although opinions are varied among authors whether the Unazuki Schist should be placed in the Hida Belt (TT) or in the Hida Gaien Belt (KT & NM) sections, this chapter will describe the Unazuki Schist in the Hida Belt section.

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.
