English

Subject field(s)
  • Tectonics
DEF

... all movement of the crust produced by earth forces, including the formation of ocean basins, continents, plateaus, and mountain ranges, etc.

CONT

The volatiles responsible for pegmatite and hornblendite development may have been derived from adjacent, contemporaneous granitoid rocks during tectonism.

OBS

Orogeny and epeirogeny are major subdivisions [of diastrophism].

OBS

tectonism: term used at Natural Resources Canada - Earth Sciences Sector.

French

Domaine(s)
  • Tectonique
DEF

Ensemble des déformations et des dislocations subies par de vastes parties de l'écorce terrestre.

CONT

Les éléments volatils à l'origine de la formation de pegmatite et de hornblendite ont peut-être été libérés par des roches granitoïdes contemporaines situées à proximité au cours d'un épisode d'activité tectonique.

OBS

Record 5 2006-11-15

English

Subject field(s)
  • Petrography
  • Geochemistry
DEF

An ultramafic plutonic rock consisting essentially of clinopyroxene and up to 50 percent olivine.

CONT

The Turnagain ultramafic complex is an Alaskan-type complex of possible Late Triassic age. It has a central zone of dunite and an outer zone of wehrlite, olivine clinopyroxenite, clinopyroxenite, dunite, hornblendite(rare), and basic hornblende and plagioclase-bearing rock(rare).... Olivine is most magnesian... in the central dunite, and most iron-rich... in olivine clinopyroxenite.

OBS

All of the clinopyroxenites may be olivine- and phlogopite-bearing with olivine surrounding pyroxenes. In some variants, termed olivine-clinopyroxenites, olivine is a major component (20-35 volume %) with only minor phlogopite (up to 2.5% ...). Rocks with higher amounts of phlogopite (12-31 volume %) and less than 8 volume % olivine are termed phlogopite-clinopyroxenites ...

OBS

olivine clinopyroxenite: term used at Natural Resources Canada - Earth Sciences Sector.

French

Domaine(s)
  • Pétrographie
  • Géochimie
CONT

Le complexe ultramafique Turnagain est un complexe de type «alaskan» d'âge triassique supérieur possible. Il est formé d'une zone centrale de dunite et d'une zone extérieure de wehrlite, clinopyroxénite à olivine, clinopyroxénite, dunite, hornblendite (rare), et d'une roche basique à plagioclase et hornblende (rare). [...] L'olivine la plus magnésienne [...] se trouve dans la zone centrale et celle la plus riche en fer [...] dans la clinopyroxénite à olivine.

OBS

clinopyroxénite : Roche magmatique composée de clinopyroxène.

OBS

clinopyroxénite à olivine : terme en usage à Ressources naturelles Canada - Secteur des sciences de la Terre.
