Paleoplacers, like placers, may be formed wherever vigorous water or air currents have sorted heavy and light, large and small, mineral and rock clasts resulting in the formation of lenses or layers containing heavy minerals ... and greater abundance than elsewhere in a clastic sedimentary formation. The term is generally applied only to those heavy mineral accumulations that are notably enriched in particular commodities - e.g. gold paleoplacers - and implies a provenance containing special primary sources of these commodities in addition to sources of the more common heavy minerals.  5, record 1, English, - paleoplacer

Les fluides métallifères. - [...] Les fissures permettent la circulation rapide des fluides aqueux et magmatiques qui interviennent de façon décisive dans le transport des composés métalliques. Le magma silicaté est l'un des fluides qui transportent les métaux. Une fois les éléments métalliques proches de la surface, le relais est pris par d'autres fluides, tels que l'eau s'échappant des magmas, la vapeur, l'eau de mer et celle des nappes phréatiques. [...] À mesure que la composition des fluides varie, leur capacité de transport des métaux diminue. Ainsi, lorsqu'ils traversent les roches et altèrent les minéraux, les fluides oxydants ou acides sont respectivement réduits ou neutralisés.  1, record 10, French, - fluide%20m%C3%A9tallif%C3%A8re
