On the cross-checking of fission track method and K-Ar method for age dating

Abstract

Recently, the cross-checking of the different age dating method is one of the important study on the geology. In this report, K-Ar dating on granitic rocks was already reported by Kawano's group. The thin section of the same sample is examined by fission track method. The measured ages by K-Ar method and fission track method agree well each other.
