It refers to fine-grained metamorphic rocks formed through contact metamorphism, exhibiting a mosaic structure without directional orientation in the texture. Hornfels of argillaceous sedimentary origin primarily consists of minerals such as biotite, garnet, epidote, and orthoclase. Hornfels of mafic igneous origin mainly includes minerals such as plagioclase, amphibole, and diopside. Andalusite is a characteristic feature.
