Description
A database of total organic carbon(TOC)contents has been compiled for Neogene mudstones from all over Japan.Most were deposited in the Paleo-Japan Sea.We analyzed 325 samples from Hokkaido,Akita,Noto,Tottod,Shimane and Yamaguchi districts using CHNS elemental analyzers in Shimane and / or Hokkaido Universities,and compiled 724 published analyses from Hokkaido,Akita,Yamagata,Niigata,Fukushima,Noto,Hyogo,Tottori,Shimane,Yamaguchi and Okinawa.All data are presented in a table including location,age and lithofacies.A histogram of all data shows that Neogene mudstones normally have TOC contents of 0.4-0.6%.
