The U/Th ratio highlights areas where uranium and thorium abundances differ, providing insights into lithological variations and alteration patterns. The dataset is provided in NB Stereographic double (NAD83) for consistent province-wide coverage.</SPAN></SPAN></P><P><SPAN>The U/Th ratio grid was produced by dividing the compiled uranium (U) raster by the compiled thorium (Th) raster at each 200 m cell. Individual NRCan radiometric surveys were microlevled and interpolated to produce a seamless 200 m grid. 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> |
