This report provides detailed (1:63,360-scale) mapping of the Tanana A-1 and A-2 quadrangles (500 square miles; equivalent to eight 7.5-minute quadrangles). The area is part of the Manley Hot Springs-Tofty mining districts and adjacent to the Rampart mining district to the south of the Tanana B-1 Quadrangle. This report includes detailed bedrock, surficial, structural, and stratigraphic data. Based on the resulting geologic maps, field investigations, and laboratory materials analyses, the report also includes derivative maps of geologic construction materials and geologic hazards. The Tanana A-1 and A-2 Quadrangles and surrounding area comprise several isolated mountainous ridges in the western Yukon-Tanana Upland...

The Alaska Geologic Materials Center (GMC) in Eagle River holds non-proprietary rock core and cuttings that represent over 13 million feet of exploration and production drilling in Alaska. Additionally, the collection holds more than 252,000 linear feet of diamond-drilled hard-rock mineral core, representing more than 1,800 exploratory boreholes; 76,000 linear feet of oil and gas core and rock samples from more than 1,650 exploratory or production wells; samples for geotechnical boreholes; and numerous surface rock and sediment samples. The collection also includes extensive geochemical data and processed material derived from this rock. This publication represents the GMC inventory in accessible, intuitive digital...

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...
