説明

K-Ar age was determined to be 54.4 ± 2.7Ma for the alteration envelope of a quartz-calcite-molybdenite vein at the Nakatatsu mine. The sample for this study is composed of muscovite of which closure temperature is included by the range of the homogenization temperature of the fluid inclusion of quartz-calcite-molybdenite veins. Thus the age of 54.4Ma is considered to represent the timing of the molybdenum mineralization at the Nakatatsu mine.
