Bedrock geologic map of the eastern Moran area, Tanana B-6 and C-6 quadrangles, Alaska

Raw Data File 2022-11, Bedrock geologic map of the eastern Moran area, Tanana B-6 and C-6 quadrangles, Alaska, presents a geologic map of the eastern Moran geologic map area, which is 150 miles west of Fairbanks, Alaska, north of the Yukon River between the communities of Ruby and Tanana. Historical and active placer mines in the Melozitna mining district, which encompasses the Moran Dome area, have produced more than 12,000 ounces of gold and an undetermined amount of tin, yet little is understood about sources for the placer metals, or the area's gold and polymetallic lode occurrences. During the summer of 2011, geologists from the Alaska Division of Geological & Geophysical Surveys' Minerals Resources Section carried out a geologic field survey, including mapping and sampling of the 301-square-mile eastern Moran area in the Tanana A-6 and B-6 quadrangles, Alaska. The mapping is part of an integrated program of airborne geophysical surveys followed by geologic mapping; it gives geological context to the Moran airborne geophysical survey and provides basic information critical to understanding Alaska's geology and mineral-resource potential. The complete report, geodatabase, and ESRI fonts and style files are available from the DGGS website: http://doi.org/10.14509/30884.

High-resolution lidar data for infrastructure corridors, Wiseman Quadrangle, Alaska

In advance of design, permitting, and construction of a pipeline to deliver North Slope natural gas to out-of-state customers and Alaska communities, the Division of Geological & Geophysical Surveys (DGGS) has acquired lidar (Light Detection and Ranging) data along proposed pipeline routes, nearby areas of infrastructure, and regions where significant geologic hazards have been identified. Lidar data will serve multiple purposes, but have primarily been collected to (1) evaluate active faulting, slope instability, thaw settlement, erosion, and other engineering constraints along proposed pipeline routes, and (2) provide a base layer for the state-federal GIS database that will be used to evaluate permit applications and construction plans. The normalized digital surface models (nDSM) represent the above ground elevation of the highest laser return with all vegetation included.

Digital compilation of geochemical data for historical samples from occurrences of strategic and critical elements in Alaska: Part II - Platinum group elements (PGE)

The State of Alaska's Strategic and Critical Minerals (SCM) Assessment project, a State-funded Capital Improvement Project (CIP), is designed to evaluate Alaska's statewide potential for strategic and critical mineral resources. The SCM Assessment project is being implemented by the Alaska Division of Geological &amp; Geophysical Surveys (DGGS), and involves obtaining new airborne-geophysical, geological, and geochemical data. For the geochemical part of the SCM Assessment project, thousands of geochemical-sample analyses and locations from historical U.S. Bureau of Mines (USBM), U.S. Geological Survey (USGS), Bureau of Land Management (BLM), DGGS, Alaska Territorial Department of Mines, Alaska Division of Mines and Minerals, and Bureau of Indian Affairs (BIA) reports are being compiled into digital format by DGGS. The objective is to update the State of Alaska's statewide digital geochemical database in order to more clearly identify areas with SCM potential. For this report, DGGS digitally compiled sample and analyses documentation, geochemical assays, and location information for more than 22,500 historical samples that were originally collected to investigate occurrences of strategic and critical elements throughout Alaska.

Geochemical, major-oxide, minor-oxide, trace-element, and rare-earth-element data from rock, stream sediment, and pan-concentrate samples collected in 2011 in the William Henry Bay area, Juneau C-4 and D-4 quadrangles, Southeast Alaska

Mineral-resources personnel from the Alaska Division of Geological &amp; Geophysical Surveys conducted reconnaissance sampling of the William Henry Bay area in the Juneau C-4 and D-4 quadrangles, August 9-13, 2011. This sampling project was part of a statewide assessment of Alaska's potential for rare-earth element mineralization. During the William Henry Bay field project 46 rock, sediment, and heavy-mineral concentrate samples were collected for geochemical analysis (geochemical, major oxide, minor oxide, trace element, and rare earth elements).

Bedrock geologic map of the Chulitna region, southcentral Alaska

This map is the result of field investigations by DGGS in 1997 and 1998. This geologic map and report supersede the previously released Public Data File 99-24B, Preliminary interpretive bedrock geologic map of the Healy A-6 Quadrangle, southcentral Alaska. The current map has been updated to include mapping of areas adjacent to the Healy A-6 Quadrangle, newly interpreted bedrock units based on newly acquired analytical, paleontologic, and Ar40/Ar39 data. Ages for the rock units were modified. Field investigations were part of a two-year mapping program to provide geologic ground truth for airborne geophysical surveys flown by DGGS in the Chulitna region of southcentral Alaska during 1996.

This geophysical survey is located in western Alaska on the Seward Peninsula in the Council and Nome mining districts, about 750 kilometers west of Fairbanks, Alaska and about 50 kilometers east of Nome, Alaska. Frequency domain electromagnetic and magnetic data were collected with the DIGHEMV system in August 2002. A total of 4558.9 line kilometers were collected covering 1649.1 square kilometers. Line spacing was 400 meters (m). Data were collected 30 m above the ground surface from a helicopter towed sensor platform ('bird') on a 30 m long line. The data, as well as additional metadata, are available from the DGGS website: http://doi.org/10.14509/30172.

Lidar-derived elevation data for upper Barry Arm, Southcentral Alaska, June 26, 2020

The Alaska Division of Geological & Geophysical Surveys (DGGS) used aerial lidar to produce a classified point cloud, digital terrain model (DTM), surface model (DSM), and intensity model of land areas in northern Barry Arm, northwest Prince William Sound, Alaska, during near snow-free ground conditions on June 26, 2020. The goal of the survey is to provide high quality, modern topographic data in the recently deglacierized part of Barry Arm where significant landslide hazards exist. Aerial lidar and ground control data were collected on June 26, 2020, and subsequently processed in Terrasolid and ArcGIS. Ground control was collected on June 26, 2020, as well. All files can be downloaded free of charge from the Alaska Division of Geological & Geophysical Surveys website (http://doi.org/10.14509/30589).

Top Mesozoic unconformity subcrop map, Cook Inlet basin, Alaska

This map shows the subcrop pattern of the Mesozoic rock units present at the top Mesozoic unconformity (also commonly referred to as the base Tertiary unconformity) in Cook Inlet basin, Alaska. The subcrop is projected onto the top Mesozoic unconformity depth surface of Cook Inlet basin, Alaska, published by Shellenbaum and others (2010). Publicly available geologic and geophysical data from multiple sources were collected, interpreted, and integrated into the subcrop map. Formation picks at the top Mesozoic unconformity were determined for 109 wells. Mesozoic horizons from two regional marine two-dimensional (2-D) seismic datasets (approximately 3,300 miles) were interpreted. Eight map units were established for the Mesozoic subcrop map: Kaguyak-Matanuska Formations, undivided; Naknek Formation; Chinitna Formation-Tuxedni Group, undivided; Talkeetna Formation; Talkeetna-Border Ranges ultramafic and mafic complex (BRUMC), undivided; Pogibshi-Port Graham formations, undivided; plutonic rocks, undivided; and metamorphic rocks, undivided. This map was prepared as part of a multi-year effort by the Alaska Department of Natural Resources.
