Une métasomatose avec imprégnation de minéraux métallifères dans les calcaires, facilement solubles, ou dans des grès, facilement perméables, s'est effectuée sur une grande échelle dans certains gisements, concurremment avec un remplissage des vides existant dans ces roches. Pour les calcaires, la substitution se traduit quelquefois par une dissolution irrégulière suivie d'une précipitation de substances métallifères remplissant les vides produits. Mais elle consiste, souvent aussi, en une imprégnation conservant la structure initiale de la roche [...] ou la transformant complètement suivant les points, c'est-à-dire en une métasomatose au sens strict. Le terme gisement de «substitution» est donc plus large que celui de gisement par métasomatose, puisqu'il peut couvrir des mécanismes par précipitation, analogues à ceux des remplissages de vides filoniens. 7, record 3, French, - gisement%20de%20substitution

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