A 1000\u202fm grid of airborne radiometric thorium (Th) concentrations for the Sussex survey area, New Brunswick (1991).<\/SPAN><\/SPAN><\/P>

This dataset represents thorium (Th) concentrations measured during the Sussex airborne radiometric survey flown in 1991 at 1000\u202fm line spacing. Thorium 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.<\/SPAN><\/SPAN><\/P>

The Sussex_Th raster was produced by microlevelling line-to-line variations in the original survey data and interpolating the results to a seamless 1000\u202fm grid. The final raster was delivered as a .ers file in NB Stereographic double (NAD83).<\/SPAN><\/P>

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.<\/SPAN><\/P><\/DIV><\/DIV><\/DIV>", "name": "Geophysics_Radiometric_Individual/Sussex_Th", "description": "
