    Tertiary deposits of the Oga peninsula in Akita prefecture affords an almost complete record of successive sediments The Tertiary stratigraphy of the peninsula has been studied by many geologists since 1892 and considered by them as a type locality of the Akita oilfields The writer who worked the geology of the peninsula during last six years wishes to propose the following revision of stratigraphic sequence of the Tertiary system in the peninsula in view of the cycle of sedimentation in descending order

    In reference to the petroleum geology the Hunakawa group is most important the Kitaura and the Minamihirasawa formations being the oil-bearing deposits
    The Oga peninsula is divisible into three different blocks on the basis of geologic structures. The west block is composed of marginal deposits and is faintly folded The middle which is seperated distinctly by the Minamihirasawa fault from the west and by the Hamamaguchi Wakimoto line from the east is monoclinally structured taking NW-SE strike and NS dip In the east the heavy Hunakawa group is normarly folded
    As a result of both stratigraphical and structural considerations of Tertiary deposits in the peninsula, a hopeful oil-productive fileld
    probadlly develops east of the Hamamaguchi-wakimoto line In other words the productive oil-field of Akita may extend from Yabase to the Mt Kampu district crossing the Lake Hachiro.

    I went to America to inspect oil fields by the order of G. H. Q. for three months arriving San Francisco on November 26, and leaving there on March 3. I spent two months in Los Angeles and 3 weeks in Dallas, Houston, and Midland, Texas. I called on Bureau of Mine, Supply and Service Companies, and some Oil Companies, and by the benefit of them, I could get so many new knowledges and could inspect some oil fields.

    During his three months trip in California and Texas, the writer recognized remarkable progress of the production technics. Followi ng factors may be considered as the reason of this progress;
    1. Position of oil industry in U.S.
    2. Enormous power of industries as a background of oil industry
    3. Fare Competition
    4. High grade differentiation of technics
    The fourth factor is the only one which is able to improve andshould be improved.
