PART 2: MINERAL COMPOSITION OF SEDIMENTARY ROCKS IN OIL FIELDS OF JAPANKoichi AOYAGI1968 年 3 巻 3-4 号 p. 54-69_3
発行日: 1968年
公開日: 2011/09/20
ジャーナル フリーAs the result of X-ray calibration based on the internal standard method, the mineral composition of the sedimentary rocks of oil fields in Hokkaido, northwestern Honshu and Kanto area, Japan has become clear. The writer briefly explains the mineral composition of each formation and describes the specific mineralogical character of these formations in each area.抄録全体を表示PDF形式でダウンロード (1980K) -
PART 3: GEOLOGICAL FACTORS AFFECTING THE MINERAL COMPOSITIONS OF SEDIMENTARY ROCKSKoichi AOYAGI1968 年 3 巻 3-4 号 p. 70-86
発行日: 1968年

ジャーナル フリーIt seems clear that variation of the mineral composition of sedimentary rocks originates from various geological, geochemical and geophisical factors. It is considered that source materials of a specified geological age which were derived from volcanic and other detritus will be deposited in a sedimentary basin of marine or continental environmental conditions, and may gradually have their mineral components changed by diagenesis. From a sedimentological point of view, it is considered that factors such as ocean currents and submarine configuration will be considered. Especially, source materials, depositional environmental conditions and diagenesis are important factors to cause variation of the mineral composition of sedimentary rocks. The writer will discuss the relations between the geological factor and the mineral composition of sedimentary rocks in Japan.抄録全体を表示PDF形式でダウンロード (1280K)
