This geological map shows: the subdivision of the Lower Aldridge, distribution of the Lower Aldridge - Middle Aldridge contact, the Sullivan horizon, and distribution of key marker units within the Middle Aldridge. The St. Mary map area (1:50 000-scale) is underlain mainly by Middle Proterozoic Aldridge Formation and younger overlying Purcell Supergroup rocks. The world-class Sullivan, sedex Cu-Pb-Zn deposit is located within the Aldridge Formation, along the eastern edge of the map sheet. Numerous base metal and precious metal veins, stratiform base-metal occurrences, and pegmatites of the Hellroaring Creek stock are located farther west.
GIS files for download, including Manifold MAP, ESRI Shape and KML files, are available in Geofile 2007-2, Belt-Purcell Metallogenic Data and Map by D.G. MacIntyre. Also available is an interactive compilation map on MapPlace: Belt-Purcell Metallogenic Map.
