English

Subject field(s)
  • Petrography
DEF

Sedimentary strata composed largely of sandstone, siltstone, and shale, with locally thin units of conglomerate, limestone, or marl, that are predominantly red in color due to the presence of ferric oxide (hematite) usually coating individual grains.

CONT

Sandstone-uranium-vanadium-base metal deposits ... are found in terrestrial sediments ... As a result, the host rocks are often red in color and for this reason copper deposits of this type are commonly referred to as "red bed copper." ... copper mineralization ... is widespread in red bed successions though it is not often up to ore grade.

OBS

red beds; redbeds; continental redbeds: terms used in the plural when collectively used to mean a whole series or succession of strata.

English

Subject field(s)
  • Copper Mining
  • Metals Mining
CONT

Diagenetic sedimentary copper deposits ... are divided into two subtypes: "Kupferschiefer-type" which occur in rocks deposited in paralic marine (or large-scale saline lacustrine) environments, and "redbed-type" which occur in rocks deposited in continental environments.

CONT

In the east African rift valleys, red bed type deposits are common with conglomerate fans along the escarpments.

CONT

Red bed uranium, vanadium, copper, lead and silver deposits are generally accompanied by bleaching.

Key term(s)
  • red bed-type deposit

French

Domaine(s)
  • Mines de cuivre
  • Mines métalliques
CONT

Les associations de minéralisations à des végétaux continentaux sont fréquentes dans les gisements de type red-beds(cuivre, uranium, vanadium) et d’une manière plus générale dans les gisements de type pénéconcordant(plomb-zinc). [...] Parmi les grands gisements métallifères liés à des matières organiques, les gîtes de cuivre-plomb-zinc de la famille «Kupferschiefer»(Allemagne-Pologne, Zambie, etc.) et les gîtes de type red-beds(uranium, plomb-zinc) sont parmi les plus représentatifs.

CONT

En ce qui concerne les gîtes pénéconcordants, il est peut-être utile de distinguer : Les gîtes de type red-beds qui correspondent à un épisode biostasique, réduit géographiquement et stratigraphiquement dans une phase rhexistasique; les gîtes pénéconcordants de type «non red-beds» [...]

CONT

Les gisements d’uranium de type «Red beds» plateau du Colorado. - Ces gisements, connus depuis 1898, fournissent aujourd’hui la majeure partie de l’uranium traité aux U.S.A. [...] Les gisements sont surtout répandus à travers tout le plateau du Colorado et répartis entre quatre États : Arizona, Colorado, New Mexico et Utah [...]

CONT

Gîte d’uranium du type «Red beds».

OBS

Record 3 1996-04-30

English

Subject field(s)
  • Copper Mining
  • Geomorphology and Geomorphogeny
DEF

sedimentary copper restricted to one or more horizons in red beds and sometimes extending for great distances. The outstanding example is the Kupferschiefer of Germany and Poland.

CONT

Sandstone-uranium-vanadium-base metal deposits. - These deposits are found in terrestrial sediments, frequently fluviatile, which were generally laid down under arid conditions. As a result, the host rocks are often red in colour and for this reason copper deposits of this type are commonly referred to as "red bed coppers."

CONT

Conformable deposits of copper occur in some sandstones which were laid down under desert conditions. As these rocks are frequently red, the deposits are known as red bed coppers.

CONT

Red bed coppers are well developed in upper Palaeozoic aulacogens of the USSR and uranium mineralization is also present in some aulacogens.
