在500 ~ 950 ℃和7 ~ 33 kb的压力范围内，测定了硬柱石-蓝晶石+石英+水蒸气和蓝晶石+硅线石+石英-钙长石+水蒸气的平衡。结果表明，在5.4 kb和410°C下，存在一个不变点，包括硬铝石、钙长石、锆石、硅线石、石英和蒸气相。根据现有资料估算了地质意义范围内的平衡硬铝石-钙长石+水的过程。讨论了该方法在区域变质作用和岩基形成机制研究中的一些应用。
The equilibriums lawsonite ⇌ zoisite + kyanite + quartz + vapor and zoisite + sillimanite + quartz ⇌ anorthite + vapor have been determined in the temperature range 500° to 950°C and in the pressure range 7 to 33 kb. The results indicate an invariant point involving the phases lawsonite, anorthite, zoisite, sillimanite, quartz, and vapor at 5.4 kb and 410°C. The course of the equilibrium lawsonite ⇌ anorthite + water in the range of geologic interest has been estimated from the present data. A few applications to regional metamorphism and the mechanism of batholith formation are discussed.
