Form of deposit and associated structures, zoning and distribution of ore minerals.

Les roches sont surtout modifiées aux surfaces de contact car la température y est la plus élevée. À la périphérie de la roche ignée formée par le refroidissement du magma on retrouve une zone métamorphique appelée auréole de métamorphisme de contact.  8, record 1, French, - aur%C3%A9ole%20de%20m%C3%A9tamorphisme

Record number: 1, Textual support number: 2 CONT

[Le métamorphisme de contact] se développe dans les terrains sédimentaires au contact d'un massif granitique (batholite) et de ses apophyses. Les terrains encaissants sont d'autant plus profondément modifiés qu'ils sont plus près du granite, formant ainsi une succession de zones concentriques ou «auréoles de métamorphisme».  9, record 1, French, - aur%C3%A9ole%20de%20m%C3%A9tamorphisme

Metasomatic deposits... commonly are superimposed on older rocks of the intrusive complex by continuing igneous activity or fluid transport of elements of economic interest(among other) ;may be crosscutting with respect to intrusive units; and commonly have associated alteration which may be a guide to ore.  2, record 4, English, - metasomatic%20deposit

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.
