English

Subject field(s)
  • Geological Research and Exploration
  • Geological Prospecting

Recently, ground and airborne gamma-ray spectrometry surveys have been used to outline potassic alteration zones closely related to copper-gold zones in the Mount Milligan deposit in central British Columbia...

French

Domaine(s)
  • Recherches et prospections géologiques
  • Prospection géologique
CONT

Récemment, on a eu recours à des levés spectrométriques du rayonnement gamma, terrestres et aériens, pour délimiter les zones d'altération potassique étroitement associées aux zones minéralisées de cuivre-or du gisement de Mount Milligan, dans le centre de la Colombie-Britannique [...]

Record 3 2005-03-08

English

Subject field(s)
  • Analytical Chemistry
  • Atomic Physics
  • Geological Research and Exploration
  • Geological Prospecting
DEF

An analytical technique involving the use of gamma radiation, which is emitted from radioactive nuclei in discrete energies.

CONT

For those deposits... in which potassic alteration is important, gamma-ray spectrometry has proven to be a useful tool for mapping hydrothermal alteration.

OBS

The spectrum of energies and the relative intensities of the gamma rays often characterize the radio-nuclide that emits them; it is these that are determined by gamma ray spectroscopy. It is possible to identify quantitatively the elements present by their characteristic gamma ray spectra as well as to determine radioactive decay rates.

PHR

Airborne gamma-ray spectrometry.

French

Domaine(s)
  • Chimie analytique
  • Physique atomique
  • Recherches et prospections géologiques
  • Prospection géologique
CONT

Dans le cas des gîtes [...] où l'altération potassique est importante, la spectrométrie gamma pourrait s'avérer un bon outil pour cartographier la configuration de l'altération hydrothermale.

PHR

Spectrométrie gamma aérienne.
