Contact metasomatic deposits. During the crystallization of certain magmas a considerable amount of fluid escapes. This fluid may produce widespread changes near the contacts of magma with the surrounding rocks. Where such changes are caused by heat effects, without addition of material from the magma, the resulting deposits are called contact metamorphic. If appreciable material is contributed by the magma, the deposits are termed contact metasomatic. 1, record 1, English, - contact%20metasomatic%20deposit
