Subject field(s)
  • Geochemistry
  • Various Metal Ores
DEF

Said of a hydrothermal mineral deposit formed within about 1 kilometer of the Earth's surface and in the temperature range of 50°-200 °C, occurring mainly as veins [and] also said of that environment.

OBS

The term "epithermal" is commonly reserved for deposits formed on land. However, volcanogenic massive sulphide deposits (VMS) are also epithermal deposits ...

Domaine(s)
  • Géochimie
  • Minerais divers (Mines métalliques)
DEF

Se dit de phénomènes géologiques et plus particulièrement métallogéniques produits à température limitée (50 à 200 degrés C), et donc proches de la surface.

OBS

[...] il n'est pas commode de dissocier, dans la littérature, la notion d'épithermal et celle de subvolcanique-volcanique. La plupart des veines épithermales citées dans la littérature, surtout américaine, sont associées à des manifestations subvolcaniques-volcaniques [...]

PHR

Filon, gisement, gîte, système épithermal.

PHR

Minéralisation, veine, zone épithermale.

Spanish

Campo(s) temático(s)
  • Geoquímica
  • Minerales varios (Minas metálicas)
DEF

Dícese de los filones que resultan del relleno de cavidades superficiales en un terreno volcánico y a temperaturas relativamente moderadas.

CONT

La formación de los filones epitermales se debe a la precipitación de sustancias contenidas en disolución por aguas calientes y por la condensación de vapores. Adoptan el aspecto de brechas compuestas de sílice, calcita, baritina, fluorita, etc. y contienen a veces sulfuros metálicos. Pueden contener oro.
