[SGL37-P04] Subsurface structure of northern Osaka basin based on borehole database
Keywords:Osaka basin, Uemachi fault, borehole database
Kansai Geo-informatics Network has compiled a large number of borehole data and has constructed borehole database. The many borehole data have been interpreted by compared with several geological investigated borehole and extend the lithological and geological information in lateral direction. The distribution of interpreted marine clay layers (Ma9 to Ma13) was investigated in the northern part of Osaka. The tectonic subsidence rates represent differential subsidence around the Uemachi fault and branched flexure in detail.
This research is partly funded by the Comprehensive Research on the Uemachi Fault Zone (from FY2010 to FY2012) by the Ministry of Education, Culture, Sports, Science and Technology (MEXT).
