SKARN . Skarn is a crystalline-textured, contact metamorphic rock. It forms by significant heating and addition of elements (metasomatism) to country rocks in the immediate vicinity of an igneous intrusion (batholith, stock, sill, dike, laccolith). Carbonate rock skarns are frequently called tactites.
