Summary:Two amphiboles are recognized in the results of experimental investigations in which several different starting materials were used in order to control water content, enhance the kinetics, or demonstrate the reversibility of univariant reactions. One essentially corresponds with end-member glaucophane. The composition of the other approaches miyashiroite. The stability field of the glaucophane is defined. The phase boundaries limiting glaucophane stability are at higher P with different slopes to those derived by other workers. The data demonstrate that the iron-free glaucophane end-member does have a high-P stability. [M.S.]
