Abstract : Some authors hold that amphiboles also contain zeolitic water that is given off in the 400-500C range, which creates a corresponding additional endothermal effect in the temperature diagram. Optical pyrometer studies of 24 specimens of amphiboles of various compositions did not show the presence of zeolitic water in even a single case. The result of these studies of different amphiboles (tremolite-actinolite series, nephrites, common hornblendes, pargasite, and arfvedsonite) was to establish that their thermal properties are largely a function of alkali content.
