Record 1 2016-02-29

English

Subject field(s)
  • Geochemistry
  • Geochemical Prospecting
DEF

The process of collecting and analysing unconsolidated soil sediments in order to locate geochemical anomalies in the underlying rock and to use these to find ore bodies.

CONT

In regional geochemical soil and silt sampling surveys, samples of conventional size are less effective in detecting the dominantly particulate scheelite than are bulk samples of alluvium ... reduced to a heavy mineral concentrate.

OBS

geochemical survey :... this expression may be further modified by indicating specifically the material sampled, as, for example, geochemical soil survey.

English

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

The mapping of geochemical facies.

CONT

Geochemical surveys can be used to indicate the presence of dispersion haloes in residual soils, and anomalous contents of elements in stream and lake bottom sediments ...

CONT

Geochemical surveys for associated elements or gold itself that may indicate anomalous areas.

CONT

Geochemical surveys of lake water or till can effectively locate the peralkaline rocks likely to host deposits.

French

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

Les relevés géochimiques de reconnaissance peuvent se faire en recueillant des échantillons au hasard ou en suivant et en examinant des cours d'eau. Les relevés détaillés se font à des points situés sur un quadrillage à maille plus ou moins serrée selon le détail désiré et les résultats sont reportés avec précision sur une carte.

CONT

Les levés géochimiques des eaux lacustres ou du till permettent de localiser efficacement les roches hyperalcalines les plus susceptibles de renfermer des gîtes.
