Metasomatism is initiated by the separation of a magmatic-hydrothermal fluid released by crystallization and hydrofracturing of the pluton, which may combine with metamorphic waters to transport base metal cations and sulphur. Metasomatic fluids pass along pluton and dyke contacts, stratigraphic contacts, fractures and other permeable pathways and infiltrate the surrounding wall rocks.  2, record 1, English, - metasomatic%20fluid

Les endoskarns se développent essentiellement dans les districts où les fluides métasomatiques ont utilisé des calcaires argileux, des volcanites ou des dykes, très perméables de par leur fracturation, comme dans les gisements de fer circumpacifiques associés aux andésites.  2, record 1, French, - fluide%20m%C3%A9tasomatique

Metasomatic deposits ... occur in alkalic igneous rocks or surrounding country rocks, with mineralization superimposed on pre-existing rocks. The principal commodities recoverable from deposits of this type are niobium, tantalum, beryllium, yttrium, rare earths, gallium, uranium, thorium, and zirconium. Normally only one or two commodities carry the deposit economically, with others if recovered, as byproducts.

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 4, English, - contact%20metasomatic%20deposit
