概要

• 論文の詳細を見る

• The clay-mineral composition of the volcanic ash soil occurring in Cheju Island, Korea, has been studied by means of chemical analysis, X-ray diffraction, differential thermal analysis (DTA), thermogravimetry (TG) and electron micrography. The results obtained show that a considerable amount of allophane and appreciable amounts of gibbsite and quartz occur in clay fractions of the soil. Appreciable amounts of vermiculite, mica and kaolin minerals are also contained in clay fractions and these may exist mainly as a complicated mixedlayer mineral.
