Data layers, including geochemistry, igneous rock indices, mineral resource data, lithology, and aeroradiometrics, were used to score subwatershed areas in Alaska to analyze for the potential of six different deposit models. The subwatershed areas, 12-digit HUCs, provide almost continuous statewide coverage, are roughly similar in size, and are physiographic features with connections to earth processes. Each HUC, or hydrologic unit code, was evaluated on various data layers to score for the potential and certainty of these deposit types: REE-Th-Y-Nb, placer and paleoplacer gold, PGE, carbonate hosted copper, sandstone uranium, and Sn-W-Mo in specialized granites. These datasets contain the individual HUC scores for each data layer and the combined data scores.
