APOPHYSES (EN: apophyses, apophysis; DE: Apophysen; FR: apophyses; ES: apofisis; RU: апофизы) are the side branches from the veins, lava covers, and intrusive bodies, which have penetrated into the host rocks. Apophyses are usually formed with the rock, which is similar to the main magmatic body, but differ in fine crystalline or porphyritic structure.
