The hornfels facies occupies the portion of the metamorphic pressure-temperature space of lowest pressure and low to high temperature. It is subdivided into a low-temperature regime of albite-epidote hornfels, a medium-temperature regime of hornblende hornfels, a high-temperature regime of pyroxene hornfels, and an ultra-high-temperature sanidinite regime. The latter is sometimes regarded as a separate facies. Maximum pressures are around 2 kbar and temperat…
