The Th/K ratio highlights variations between thorium and potassium abundances within the survey area and supports interpretation of lithological variations and alteration patterns. The dataset is provided in NB Stereographic double (NAD83) for consistent integration with provincial datasets.</SPAN></SPAN></P><P STYLE="font-size:16ptmargin:0 0 0 0;"><SPAN>The WesternNB_ThK_ratio raster was produced by dividing the compiled thorium (Th) raster by the compiled potassium (K) raster at each 1000 m cell. The underlying survey data were microlevled and interpolated to produce seamless 1000 m grids prior to ratio calculation. The final raster was delivered as a .ers file in NB Stereographic double (NAD83).</SPAN></P><P><SPAN>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> |
