| Outline of Final Research Achievements |
The radiolarian age dating and detrital zircon age dating revealed two types of lithostratigraphic units in the Nishiki Group of the Akiyoshi Belt. New stratigraphic sequences of chert breccia are recognized in the Yoshiki Group, eastern Hiroshima. The Ultra Tamba Belt of the Obama area is underlain by the melange and coherent units, while the one of the estern Okayama contains highly disrupted slump deposits. The detrital zircon dating and sedimentary petrology on sandstones show that different ages of Late Paleozoic volcanic activities, which provide detrital sediments to the Akiyoshi, Ultra Tamba and Maizuru Belts.
