Geologic mapping of the Sleetmute quadrangles in southwestern Alaska utilized detailed topographic maps, aerial photographs, and field data from U.S. Geological Survey studies, with key contributions published in 1984 and supplemented by Alaska DGGS data files. The region's geology spans from the Late Proterozoic to the Holocene, with the oldest rocks informally grouped under the broadly defined Holitna Group. Most of the area is underlain by the Kuskokwim Group, a thick sequence of marine turbidites primarily dated to the Late Cretaceous. Overlying this is the Holokuk Basalt, a Late Cretaceous volcanic unit associated with granodiorite intrusions, followed by younger dikes and olivine basalt dated at 38 Ma. Quaternary deposits record four glacial advances, and the area exhibits complex folding and faulting tied to the Denali-Farewell fault system. The lower Kuskokwim region is rich in mineral resources, including placer deposits of gold and tungsten, and vein and greisen deposits containing mercury, antimony, tin, and other metals. Hydrothermal quartz veins near Fortyseven Creek host gold and scheelite, likely formed by a rhyolite intrusion. Mercury and antimony deposits, such as the Mountain Top site, occur in sheared and brecciated rocks, possibly linked to hot spring activity. Tin is found in quartz-tourmaline veins and stockworks near pluton contacts, with mineralized zones showing distinct downstream geochemical signatures.The complete report, geodatabase, and ESRI fonts and style files are available from the Alaska Division of Geological & Geophysical Surveys website: http://doi.org/10.14509/2280. Purpose: The purpose of this research was to investigate the mineralization within the lower Kuskokwim River basin in southwest Alaska. The study aimed to assess the geologic context, resource potential, and development history of these deposits. Additional objectives included evaluating local sand, gravel, and riprap resources for potential use in regional infrastructure projects.

A reconnaissance study by Cady et al. (1955) included these quadrangles. Preliminary geologic maps for Sleetmute A-6, B-5, and B-6 were published in 1984 by various authors, and geochemical maps for rock, pan-concentrate, and stream sediment samples were compiled by Robinson in the same year. Process_Date: 1995 Process_Step: Process_Description: GIS analysis and digital cartography - This data distribution package's geologic and geographic features were organized and attributed according to the AK GeMS geologic mapping schema. The data were programmatically transformed to provide download options in three formats: (1) an AK GeMS data package that includes the complete AK GeMS database and associated files, (2) a GeMS data package that is a conversion of the AK GeMS database into the base GeMS standard published by the USGS, and (3) a shapefile data package that includes two simple shapefile representations of the data.
