    At present, water supply for industrial centers on sea-sides amounts to 3 × 109 m3 per year in the quantity. But it is excessively restricted by water right of agriculture and often afflicted by water-level draw down or salt water invasion in wells and land subsidence as a result of collective pumping.
    Only regional investigation for water resources carrying out by Geological Survey prevents these disasters by offering constructive and concrete data for industrial water supply, including ground water utilization.

    In this thesis, the present author deals with the oil shale deposits in Manchuria, from standpoints of geological, petrographical and chemical studies as well as of the genesis of the oil shale deposits.
    The concluding remarks of this thesis are as follows :
    I. Peculiar distribution of oil shale deposits in Manchuria. Sediments of an isolated basins in which the oil shaleis csdeposited, are arranged in NE direction, (so-called Cinian direction) including partly in EW line. Fresh water sediments of each basin in the same line belong almost to same geological age.
    II. Classification of oil shale deposits in Manchuria. Oil shale deposits in Manchuria are newly classified into five horizons by knowledge of the latest progress of the Mesozoic stratigraphy in Manchuria.
    III. Straratigraphy of typical oil shale deposits in Manchuria. Sanshin deposit and Lokukon deposit are described in detail more than the other deposits in Manchuria.
    IV. Discussion of basement rocks. Basement rocks are an important problem especially for oil shale deposits and coal-fields. So the granite of Sanshin basement rock are carefully studied on the geological age of its intrusion at Sanshin district.
    V. Petrographical and Chemical properties. The author's conclusions are as follows : -
    1. Lotsukon oil shale belongs to mixed type (oil shale and humite) Carboniferous materials which are contained in oil shale have been proved truly as “Humite” by the author's microscopical observation and chemical analysis.
    2. Tongning oil shale ako mixed type, especially the oil shale has been proved by this chemical analysis and the character of crude oil.
    3. Solid bitumen Tamyao. Kerogen in the oil shale has altered to solid bitumen by the effect of caustic action of basaltic lava flow.
    4. Crude oil of Lotsukon oil shale is mixed base (paraffin and asphalt), but that of Fushun is pure paraffin base. The former contained larger amount of Nitrogene compared with the latter.
    5. CaO in ash of Lokukon oil shale has in large quantities. For that reason, mutual relation between yielding oil content and volatile matter, or ash content is in disorder.
    VI. Genetic consideration.
    1. The author has adopted “the theory of Algae origin”.
    2. The author classified oil shale deposits in Manchuria into many types from the conditions and environments of sedimentation in the peat-stage.
    VII. The author referred to oil shale deposits in Manchuria in each geological age from the economic point of view.
    VIII. The author briefly touched on the crustal movements and igneous activities, from Mesozoic to Tertiary age and on the character of fresh water sediments.

  • Studies on the Erosion-Volume of the Topography of Yamagata Prefecture
    Nobuyoshi USHIJIMA, Yoshihiko TAKEUCHI

    During the cycle of erosion and sedimentation, there should be a volumetric equilibrium between them. The writers have assumed the volume of sediments in basins is equal to the void space between the summit level and the present topography at each drainage area. In that case, the volume of the youngest Tertiary formation (Shibikawa stage of Plioceneage) at Shonai, Shinjo and Yamagata basin is nearly equal to the erosion volume of the topography covered by the Mogami River. In other words, the formation of the present topography has just begun at the latest Pliocene. Further writers found a key to solve the problems to determine the stage of a geomorphological development by analyzing the present topography. Lastly, there is shown a volumetric relation between the river-length (l) and erosion volume (v) in this district, v = 0.019l2 + 0.12l.
