| Research Abstract |
It has been considered that a tectonic line or a large fault is situated between the two geologic terrains. "Nobeoka Tectonic Line" is also regarded as such a fault dividing the Shimanto belt into to parts in Kyushu, Japan. Northern part is the Cretaceous Morotsuka belt and southern is the Paleogene Mikado and Hyuga belts.
"Nobeoka Tectonic Line" is believed that it passes through Mikado area. So we carried out the detail geologic survey. We find some outcrops of the very boundary between the Morotsuka and the Mikado groups. But no shear structure, i. e. fault gouge or fault breccia is observed. Moreover these two groups have concordant structures and affected the same folding. The same lithology such as chart-laminite is also found in the both groups. Therefore "Nobeoka Tectonic Line" does not exist in this area.
