| Abstract | Multiparameter downhole geophysical measurements in two representative boreholes in the eastern Athabasca Basin are compared to visual, petrographic, mineralogical, and lithogeochemical analyses of
their drill cores. Natural gamma-ray spectrometry data exhibit increased levels of radioactivity in the Read and Manitou Falls formations that relate mainly to natural thorium and, to a lesser extent, uranium abundances, whereas potassium responses
are generally low. Thorium responses in these quartz-dominated fluvial deposits are closely correlated with detrital grain-size parameters such as the per cent of grains greater than 2 mm and are therefore interpreted to relate to primary heavy
mineral accumulations and their diagenetic products (crandallite-group minerals) within coarser grained beds. Diagenetic attributes such as porosity and silicification are positively correlated with density, resistivity, and acoustic velocity.
Natural
gamma-ray logs are thus guides to stratigraphy, and other geophysical parameters calibrate ore-related alteration features, thereby facilitating integration of geological and geophysical transects. |
