Record 5 2006-12-06

English

Subject field(s)
  • Various Metal Ores
  • Mineralogy
CONT

Stratiform ores are made up of massive, "net-textured" and disseminated chromite.... Disseminated chromite occurs also in peridotite, pyroxenite, or anorthosite and, although it does not constitute ore in its own right, may be recovered where it is interlayered with massive or net-textured chromitites.

French

Domaine(s)
  • Minerais divers (Mines métalliques)
  • Minéralogie
CONT

Les minerais stratiformes sont constitués de chromite massive, de chromite à texture «réticulée» et de chromite disséminée. [...] On trouve en outre de la chromite disséminée dans de la péridotite, de la pyroxénite ou de l'anorthosite; bien que cette chromite ne constitue pas en elle-même un minerai, elle peut être récupérable là où elle est interstratifiée avec des chromitites massives ou des chromites à texture «réticulée».

Record 9 2003-11-17

English

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

The rocks situated under a deposit or other strata.

CONT

The orebodies occur in the sublayer which is clearly a later intrusion than the overlying norite with which it has a sharp contact. The sublayer magma was rich in sulphides and inclusions, of peridotite, pyroxenite and gabbro.

CONT

Sudbury ... possesses a sublayer rich in ultrabasic xenoliths probably derived from a hidden layered sequence.

French

Domaine(s)
  • Mines métalliques
  • Géomorphologie et géomorphogénie
CONT

Ce sont des gîtes d'éluvion [...] où le lessivage des couches supérieures provoque la formation d'incrustations, de concrétions ou de cimentation dans les couches sous-jacentes [...]
