Basaltic glass has been weathered to clay minerals and iron oxyhydroxides in Andosol and Loam. The order of mobility of the elements during the chemical weathering of Andosol is alkali, alkali earth elements > REE > U, Th. The release rate of these elements is smaller in Loam underlying Andosol than in Andosol. Maximum release rate of REE, U and Th from the basaltic glass in Andosol during 3000 years is estimated to be ca. 50%, 30% and 30%, respectively. However, REE, U and Th released from the basaltic glass migrated downward and accumulated in Loam, suggesting that REE, U and Th were not removed from Andosol + Loam system for a long period."},{"@language":"ja","@value":"黒ボク土, ローム層の化学分析を行うことで, 玄武岩ガラスの風化作用, 土壌化作用に伴う希土類元素 (REE) (Am, Cmの化学的類似元素), ウラン, トリウムの長期的挙動について調べた. 黒ボク土中では, 玄武岩ガラスは変質し, 粘土鉱物, 水酸化鉄へと変化していく. これらに伴うアルカリ元素, アルカリ土類元素の溶脱率は大きい.
