ABSTRACT

The D/H ratios of hornblendes, epidotes, zoisites and white micas in the epidote-amphibolites from four localities in Japan have been determined together with the chemical compositions. The order of enrichment for deuterium in these minerals is as follows: epidote > white mica > hornblende > zoisite. A quite different situation for D/H ratios between coexisting zoisite and epidote is pointed out.
