Abstract
A method has been developed for extraction of hydroxyl oxygen from hydroxyl-bearing silicate minerals for oxygen isotopic analysis. The δO^(18) of oxygen of the OH groups is significantly different from that in the rest of the mineral structure. The isotopic fractionation between the two types of sites has the potential to be a sensitive geothermometer. Several δO^(18) values were obtained for oxygen of the OH attached to different silicate structures as well as for two muscovite samples with quantitatively estimated different temperatures of formation. The 1000 In α (mineral-OH) values ranged from 5.2‰ for muscovite to about 12.6‰ for kaolinite and chlorite.
