A fine-grained metamorphic rock composed of a mosaic of equidimensional grains without preferred orientation and formed by contact metamorphism. Porphyroblasts or relict phenocrysts may be present in the granoblastic matrix. Variants include: calc-silicate hornfels, pelitic hornfels, magnesian hornfels, etc.
