Abstract | Airborne gamma-ray spectrometry provides measurements of the surface concentrations of potassium (K), equivalent uranium (eU) and equivalent thorium (eTh). The resulting radiometric maps present
intricate spatial variations that are controlled among other things by the complex surface processes and the inherent statistical fluctuations of radioactive decays. To enhance the readability of the radiometric images, radiometric domains,
spatially-restricted areas presenting a distinctive signature, can be traced to provide local baselines of the surface concentrations of the natural radioelements. This approach was applied to airborne gamma-ray survey data from the "Eastern
Athabasca Basin" survey, in Saskatchewan. Ground spectrometry measurements were conducted in 2013 within the radiometric domains that were identified and compare well with domain averages calculated from the airborne survey data. |
Summary | (Plain Language Summary, not published) Airborne gamma-ray spectrometry (AGRS) provides direct measurements of the earth surface's concentrations of potassium (K), Uranium (U) and Thorium (Th).
This information, usually presented on a map, is very useful for geological mapping and mineral exploration. This poster present a methodology, that was applied to AGRS data from the Athabasca Basin area, to enhance the readability of AGRS maps by
reducing the complexity of the measurements in a set of spatially-restricted areas. It will help end-users involved in geological mapping and exploration make better use of the wealth of geophysical survey data distributed freely by the Geological
Survey of Canada. |
