Abstract

Thermal metamorphism of Silurian sediments at a gabbro contact took place under pyroxene-hornfels facies conditions. The most common hornfels is essentially composed of pyroxene and labradorite; its chemical composition compares with that of average gabbro. The hornfels is believed to have been metasomatically altered, probably basified, during metamorphism.
