Abstract
Bowen and Tuttle (1949) first directed the attention of experimental petrologists to anthophyllite by producing it as a metastable breakdown product of talc; these authors were unable to demonstrate a stability field for anthophyllite and suggested that its production might depend on the absence of H2O-rich fluid. Yoder (1952) experienced similar results in his investigation of the system MgO-Al2O3-SiO2-H2O, and advanced the concept of the “water deficient region,” that is, chemographic space in which a stable fluid phase is prohibited; Yoder suggested that anthophyllite might be confined to such a compositional region, at least in the investigated system.
