A 250 m grid of airborne radiometric potassium (K) concentrations for the Mount Pleasant Caldera (West) survey area, New Brunswick (1988).

This dataset represents potassium (K) concentrations measured during the Mount Pleasant Caldera (West) airborne radiometric survey flown in 1988 at 250 m line spacing. Potassium values are derived from gamma-ray spectrometry measurements and reflect near-surface lithology and alteration patterns within the survey area. The dataset is provided in NB Stereographic double (NAD83) for consistent integration with provincial datasets

The MountPleasant_K raster was produced by microlevelling line-to-line variations in the original survey data and interpolating the results to a seamless 250 m grid. The final raster was delivered as a .ers file in NB Stereographic double (NAD83)
