The argon retention of obsidian was studied with respect to the degree of hydration. It is found that there is a negative correlation between them. Consequently, forK-Ar dating, it is recommended to use obsidians whose H20(+)contents are small, say, below about0.5%of weight. It is also found that a rhyolite sample shows poorer argon retentivity than that of a fresh obsidian. The probable age of obsidian at Wada Toge (pass) is about0.9-1.1m. y..
