Eagle airborne magnetic and radiometric geophysical survey

Eagle airborne magnetic and radiometric geophysical survey, Geophysical Report 2021-2 v. 2, covers parts of the Nulato Quadrangle west of Fairbanks, Alaska. Magnetic and radiometric data were collected with a helicopter between June 4 and 17, 2024, by EON Geosciences Inc. The survey contains a single block covering 1,975 km², which includes an infill block with tighter line spacing located in the northcentral portion of the block. A total of 6,459 line-kilometers were collected. The magnetometer was installed inside the stinger attached to the helicopter nose, and the airborne gamma-ray spectrometer was mounted on the interior floor of the helicopter cabin. The block was flown with a line spacing of 400 m, and the northcentral infill block was flown with 200 m spacing. Tie-lines for magnetic leveling were flown at 1,600 m spacing. We updated this dataset in 2025 to refine processing, removing artifacts and excess noise present in the final products provided by the original contractor. The raw data were reprocessed by Baigent Geosciences. The International Geomagnetic Reference Field correction was recalculated accounting for aircraft height, and the data were relevelled using Baigent Geosciences software. A complete and detailed report on the reprocessing steps undertaken is included in the publication documents. The result of the reprocessing is that leveling artifacts have been removed and the data now display finer features, including well-defined lineaments and other anomalies which were not present in the original contractor grids. The data, as well as additional metadata, are available from the DGGS website: http://doi.org/10.14509/31694.

Geologic and geochemical investigations, Nail Ridge area, northwest Big Delta Quadrangle, Alaska

Geologic and geochemical investigations, Nail Ridge area, northwest Big Delta Quadrangle, Alaska, Public Data File 85-38, describes the geology of a 60 km2 area in the northwestern Rig Delta Quadrangle, covering parts of the Big Delta C-2, C-3, D-2, and D-3 Quadrangles. Fieldwork conducted in June 1983 as part of the Chena Project involved DGGS, BOM, USGS, and the University of Alaska. The study includes geochemical analyses of 50 rock samples, 29 stream sediments, and 29 pan concentrates. A key feature is a 12-km-long, 610-m-thick ultramafic body of possible Permian age overlying greenschist-facies metamorphic rocks, with carbonate alteration likely caused by low-temperature CO2-rich fluids. Results show no significant chromite, platinum-group elements, or gold; one silica-carbonate occurrence is anomalous in copper, antimony, arsenic, and silver but is limited in extent. A large magnesite-rich zone exists at Nail Ridge, though its remote location and alternative sources reduce its economic potential.

Geology and geochemistry of the Inmachuk River map area, Seward Peninsula, Alaska

Geology and geochemistry of the Inmachuk River map area, Seward Peninsula, Alaska, Geologic Report 23, presents a geological overview of the Inmachuk map area, a 110-square-mile region in Alaska's northern Seward Peninsula. Fieldwork was conducted from July 13 to July 31, 1965. Mineral deposits include lead-zinc lodes and placer gold near Hannum Creek, gossan zones to the southeast, and reported placer tin in nearby creeks. Additional placer gold occurs along the Inmachuk River, just east of the mapped area. The terrain consists of tundra-covered low hills underlain by schist, phyllite, and marble. A structural dome in the southern area exposes thick marble intruded by Mesozoic(?) granite. Mineralization includes marble-hosted pyrite-lead-zinc at Ear Mountain Creek and fault-controlled gossan zones with low metal values. Soil and stream sediment anomalies near Hannum Creek suggest detrital lead transport. Weak lead and tin anomalies on the dome's flanks may indicate bedrock sources, though no surface ore was found.

The central Kuskokwim region, Alaska

The central Kuskokwim region, Alaska, Professional Paper 268, synthesizes the geology, ecology, and mineral resources of Alaska's central Kuskokwim region. Located within a tectonically active mobile belt, the area features over 60,000 feet of sedimentary and volcanic rock, shaped by repeated mountain-building, faulting, and intrusive events from the Precambrian through the Cenozoic. Key igneous rocks include andesite, basalt, rhyolite, quartz monzonite, and diabase, with associated metamorphic zones. Mineral deposits-especially quicksilver, gold, and tungsten-are concentrated in rolling terrain near intrusive contacts. Geomorphic surfaces and active faults reflect ongoing uplift and erosion. The region's rich geologic history and resource potential make it a significant area for exploration. This data release is a conversion of the originating geospatial data published by the USGS and may include minor modifications necessary for schema compliance. The dataset contains geologic, structural, stratigraphic, and geochronologic data organized according to the GeMS and AK GeMS mapping schemas. The complete report, geodatabase, and ESRI fonts and style files are available from the Alaska Division of Geological & Geophysical Surveys website: http://doi.org/10.14509/3818.

Igneous and metamorphic rocks of the Serpentine Hot Springs area, Seward Peninsula, Alaska

Igneous and metamorphic rocks of the Serpentine Hot Springs area, Seward Peninsula, Alaska, Professional Paper 1079, describes the geology of the Serpentine Hot Springs area of the Seward Peninsula, Alaska, emphasizing the petrology, petrography, and mapped relations of lithologic units within a composite, epizonal biotite granite stock and the regionally metamorphosed metasedimentary rocks that surround it. Geologic relations are combined with reconnaissance geochemical data to define mineralized zones and their spatial associations with the granite stock. Petrochemical variations within the granite are integrated with field observations to enhance understanding of magmatic evolution and mineralization processes. The synthesis of lithologic, petrographic, and geochemical data provides insight into the tectonic and thermal history of the region, contributing to broader interpretations of crustal development in western Alaska.

Geology and mineral resources of the Russian Mission C-1 Quadrangle, southwest Alaska

Geology and mineral resources of the Russian Mission C-1 Quadrangle, southwest Alaska, Professional Report 109, presents a geologic map of the Russian Mission C-1 Quadrangle in southwestern Alaska, covering 522 km2 near the western edge of the Kuskokwim Mountains. Fieldwork conducted between 1985 and 1988 included 1:63,360-scale mapping and mineral-resource investigations. The area features a mix of rounded ridges and sediment-filled lowlands, with the Russian Mountains massif rising to 1,057 m and hosting alpine glaciation during the Quaternary. Fifteen bedrock units, from Pennsylvanian to late Tertiary, were analyzed using petrography, geochemistry, and radiometric methods. Fourteen Quaternary-age surficial units were identified through field and photogeologic techniques.

Surficial geology of the lower Pilgrim Valley and vicinity, western Seward Peninsula, Alaska

Surficial geology of lower Pilgrim Valley and vicinity, western Seward Peninsula, Alaska, Alaska Open-File Report 140, presents the results of surficial geologic mapping and aerial photo interpretation conducted between 1979 and 1981 in the Pilgrim Hot Springs area of the Seward Peninsula, Alaska. DGGS geologists delineated Quaternary deposits and geomorphic features shaped by glacial, fluvial, lacustrine, and eolian activity. The map identifies surficial units such as alluvium, colluvium, outwash, loess, peat, and till; and documents landforms including eskers, moraines, terraces, kettles, and aufeis. This publication supports geologic hazard assessment, resource exploration, and land-use planning.

Preliminary geologic map and data tables of the Ophir C-1 and western Medfra C-6 quadrangles, Alaska

Preliminary geologic map and data tables of the Ophir C-1 and western Medfra C-6 quadrangles, Alaska, Public Data File 97-46, presents preliminary geologic findings from 1:63,360-scale mapping conducted by DGGS in May and June 1996 across the Ophir C-1 and western Medfra C-6 quadrangles in western Alaska. The study documents bedrock units from the Ruby and Innoko terranes, Cretaceous flysch, and the Cripple Creek Mountains volcano-plutonic complex, along with 17 unconsolidated surficial deposits. DGGS identified complex structural relationships, including multiple folding events and fault systems, and began radiometric dating to refine the geologic timeline. Economic geology highlights include placer gold production and mineralized zones in the Cripple Creek Mountains, where gold-antimony veins and breccia zones align with key fault intersections.
