About Hornfels
Defined by Robertson (1999) as a fine grained variant of granofels, formed by contact metamorphism.
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.
