A 50 m grid of airborne radiometric potassium (K) concentrations for New Brunswick
This dataset represents potassium (K) concentrations across New Brunswick at 50 m resolution, derived from a compilation of NRCan airborne radiometric surveys originally flown at 1000 m line spacing (base compilation) and enhanced with higher-resolution surveys flown at 300 m line spacing or less. Potassium values are obtained from gamma-ray spectrometry measurements and reflect near-surface lithology and alteration. The dataset is provided in NB Stereographic double (NAD83) for consistent province-wide coverage.
The potassium grid was produced by compiling individual NRCan radiometric survey grids, microlevelling line-to-line variations, and interpolating the results to a seamless 50 m cell-size raster. The final raster was projected to NB Stereographic double (NAD83) and delivered as individual grid.
The dataset is not updated regularly. Updates occur only if new reprocessing, corrections, or additional surveys become available. As of now, the compilation represents the most recent processing as of December 2025.
