Ground and airborne gamma-ray spectrometry was widely introduced in the late s and s, following military declassification, and continues to be useful for geologic and alteration mapping purposes as well as the direct detection of U and rare-earth element deposits occurring at or very near surface (Foote, ; Darnley and Grasty, Airo, M.‐L.

Abstract. A bedrock data model was generated for the EXTECH-II project so that bedrock geology maps prepared by many mapping teams, and the most significant un.
In Olaniyan et al., the 3‐D model was obtained by integrating a compilation of surface and subsurface geologic data with high‐resolution airborne magnetic and gravity data.
The authors evaluated qualitatively high‐resolution Bouguer gravity data with the computed field along with subsurface geologic data and created their cross section Cited by: 6.
Gamma-ray spectrometry data provide estimations of the concentrations of potassium (K), uranium (eU), and thorium (eTh) in materials at the earth surface. It has been shown that ternary color images of the K, eTh, and eU channels reflect many of the lithological variations in granite-gneiss terrain BroomeCharbonneauJaques et al.

The Sudbury Structure straddles the boundary between the Archean Superior Province to the North, and the Paleoproterozoic Southern Province to the east and south ().The origin of the structure remained enigmatic until Dietz () suggested that it is the consequence of a meteoritic impact.
