ジャーナル フリーThe importance of carbonate reservoir and source rocks is underscored by the fact that about half of the world's petroleum is produced from carbonates. In as much as stratigraphic and structural habitats of many oil and gas pools in carbonate rocks suggest indigenous origin of their hydrocarbons, many petroleum geologists are studying the origin and occurrence of petroleum in these rocks.
The writers have been studying the origin and distribution of Neogene carbpnate rocks in the Akita Oil Fields of Japan since 1967. In the present paper some data on clay minerals and organic matter present in these rocks are presented. An attempt is made to relate the chemical and mineralogic composition of these rocks to density, porosity and other parameters. The results of the present study can be summarized as follows:
(1) On the basis of clay mineral content, carbonate rocks can be grouped into those containing predominantly (a) kaolin clay or (b) montmorillonite clay. In addition, there is a group poor in clay mineral content.
(2) Carbonate rocks containing kaolin clay formed in inner-neritic depositional environment, whereas carbonte rocks poor in clay mineral content or those containing montmorillonite clay formed in outer-neritic to bathyal environments.
(3) Carbonate rocks containing kaolin clay have high density and relatively high effective porosity Carbonate rocks low in clay mineral content have high density and low effective porosity.
(4) The amounts of organic extracts, hydrocarbons and total organic carbon are approximately equal to 1/2 of those usually found in shales.
In the future the authors will attempt to correlate the Ca/Mg ratio of the carbonate portion of the rock (excluding clays) and the porosity. In addition, insoluble residue contents will be plotted versus degree of dolomitization. The amounts of clays in cerbonate rocks will also be determined quantitatively.抄録全体を表示PDF形式でダウンロード (1028K) -

ジャーナル フリーClay minerals in Pliocene sediments and weathered granite underneath taken from clay deposits around Nagoya City were examined with special reference to the genesis of kaolin minerals. Following results were obtained.
1) In weathered granite, both platy-kaolinite and long tubular halloysite occur and the ratio of the kaolinte to the halloysite is variable.
2) In Pliocene arenaceous sediments, b-axis disordered kaolinite is a predominant clay mineral and tiny tubular halloysite is often found. In Pliocene argillaceous sediments, the chief clay mineral is kaolinite which is rarely accompanied by halloysite.
Mineral transformation during weathering and diagenesis is discussed on the basis of these results.抄録全体を表示PDF形式でダウンロード (15865K) -

ジャーナル フリーThe most suitable condition about the Schollenberger's method was obtained to get the cation exchange capasity for zeolite bearing tuffs. The result is that the specimen is fully saturated with NH4+ by treating with 60 ml of 1N NH4COOH solution taking about 2 hours, and is enough extracted all of the exchanged NH4 by treating with 60 ml of 10% KCl solution taking about 2 hours.
The cation exchange capasities of many zeolite bearing tuffs were obtained by this method and the quantative values of zeolite in tuffs were presumed with the data of the X-ray reflection's intensity.
For the comparison with the data obtained by the Schollenberger's method, the Schofield's method was examined. The value obtained by the latter method is about 10% higher than the former one.抄録全体を表示PDF形式でダウンロード (966K) -
