Stratigraphic resolution: | formation | ||||
Stratigraphy comments: middle unit of shioya group, divided into two members, lower and upper. |
Lithology and environment
Primary lithology: | coarse lithified conglomerate |
Secondary lithology: | fine,medium lithified sandstone |

Includes fossils? | Y |
Lithology description: The Kanomatazawa formation is composed of conglomerate sandstone siltstone and acidic pyroclastic rocks. Lithology of the upper member is represented by mudstone in the western side whereas it is represented by coarse clastic sediments in the eastern side of the anticline. | |
Environment: | marginal marine indet. |
Glacial or sequence phase: | regressive |
Geology comments: This formation is subdivided into the lower and upper members. The two members differ from each other in their distribution as well as their lithological characteristics. The Lower member is distributed in the whole surveyed area showing similar lithology at every place. Distribution of the upper member is separated at the sekiya anticline. |
