WebSep 10, 2024 · Contact metamorphism describes the type of metamorphism attributed to increased temperature, usually from proximity to a heat source such as an intrusive magma body or a lava flow, and the rock undergoes thermal metamorphism. WebHornfels is a rock formed by contact metamorphism, a process that characteristically involves high temperatures but low pressures/depths. This facies is characterized by the following minerals: In metabasites: albite + epidote + actinolite + chlorite + quartz In metapelites: muscovite + biotite + chlorite + quartz
