And special attentions were payed to peculiar layers interlain for genesis and mineralogy. These two profiles consisted of acidic red and yellow soils which were locally calledKunigami maaji, Kunigami gravel and marl (or mudstone) in descending order. One soil profile (no. O-30) was located at Gushikawa, Gushikawa-shi of the middle part of Okinawa Island and the other profile (no. O-31) was at Bimatabaru, Nago-shi of the northern part. In the both profiles the layers ofKunigami maajisoil and Kunigami gravels which contained quartzite were red to yellowish, strongly acidic, and of light clay to sandy loam. The upper layers were considerably low in exchangeable bases, CEC, base saturation and phosphorus absorption coefficient. The major crystalline materials in the clay fraction were kaolin minerals, illite and vermiculite-chlorite intergrade, and the minor ones were vermiculite, and illite or chlorite and vermiculite irregular mixed-layer mineral. In the silt fraction the primary mineral quartz was the major constituent, and also found were feldspars and/or cristobalite in a minor quantity. On the other hand, the lower layers consisting of marl deposite at the both profiles showed grayish color, slightly deposit at the both profiles showed grayish color, slightly alkaline reaction, and clay loam to silty loam texture. They contained a small quantity of free calcium carbonate and effervesced with dilute hydrochloric acid solution. The CEC and phosphorus absorption coefficient were comparatively high and exchangeable calcium was much higher than magnesium. The major crystalline materials in the clay fraction were illite and montmorillonite accompanied by a minor amount of vermiculite, vermiculite-chlorite intergrade, chlorite and kaolin minerals. The primary mineral in the silt fraction was mainly consisted of quartz accompanied by a small amount of feldspars and cristobalite. At Gushikawa profile (no. O-30) a peculiar red colored thin layer was found between Kunigami gravel and marl deposit. It was assumed that the red layer was formed by a translocation-accumulation process of the materials from overlying Kunigami gravel to the present position. The red layer was strongly acidic and of heavy clay. Exchangeable magnesium was higher than calcium, and the CEC and phosphorus absorption coefficient were much higher in this layer than those in the overlying layer of Kunigami gravel. Neither the intergrade nore the mixed-layer minerals were identified in the clay fraction, and quartz alone was identified in the silt fraction of the red layer. The mudstone deposit overlain by the red layer was quite similar to the color of previously mentioned marl deposit. But it carried some properties of acid sulfate soil, namely it was strongly acid and contained more exchangeable magnesium than calcium and showed texture of light clay. Accordingly a remarkable difference was recongnized between the mustone and marl deposits by the contents of calcium carbonate. It was assumed that changes of substances and sedimentation condition had caused the difference in the deposits of mudstone and marl. At the Bimatabaru profile (no. O-31) thick layers containing quartzite gravels were found between Kunigami gravel and marl deposit. These layers were red and yellow in color, clay loam to loam in texture and acid to slightly alkaline in reaction. The major crystalline minerals in the clay fraction from these layers were illite and montmorillonite accompanied by a small amount of vermiculite, vermiculite-chlorite intergrade and kaolin minerals. In the silt fraction identified were quartz in a large quantity and feldspars and cristobalite in a small quantity.
