The Geologic Map Index of Alaska (Map Index) is an online, interactive web mapping application that provides access to an actively growing geographic index of geology-related maps of Alaska and adjacent areas. This online research tool provides the locations and outlines of most DGGS and U.S. Geological Survey (USGS) geologic and geophysical maps of Alaska in a single, interactive web map. It allows searches of the map database by geographic area of interest, keywords, themes, publishing agency, dates, and other criteria. The search results provide links to DGGS's comprehensive, multi-agency publications database, where users may view and download publications for free. No other geographic index of Alaska geologic...

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 & 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...

Alaska is the most seismically active region of the United States. However, little information exists on the location, style of deformation, and slip rates of Quaternary faults. This interactive map displays locations and relative activity of Alaska's faults and folds. The map offers zoom and scroll options, and multiple base map layers. Click individual fault and fold traces to view basic fault parameters: name, age, slip rate, slip sense, dip direction, mapping certainty, and mapped scale. This resource is intended to provide simple and quick means of visualizing structure locations and characteristics. Users must recognize mapping certainty and data accuracy limitations when zooming in farther than the stated...

Naturally occurring asbestos (NOA) develops in predictable geologic settings worldwide. Various geologic units throughout Alaska include rock types that could potentially host naturally occurring asbestos minerals. This report and digital data release show geologic map units throughout Alaska rated according to their interpreted potential to host NOA. To summarize locations of known asbestos occurrences, we searched the U.S. Geological Survey's (USGS's) Alaska Resource Data File (http://ardf.wr.usgs.gov) and Mineral Resource Data System (http://mrdata.usgs.gov/mineral-resources/mrds-ak.html) for references to asbestos in Alaska and compiled the resulting 62 documented asbestos occurrences. To better predict additional...

The Geologic Photos of Alaska database and online application contains photographs taken during and in support of Alaska Division of Geological & Geophysical Surveys (DGGS) projects. These photographs primarily document field sites and geomorphology statewide, usually in remote locations that are often impossible or prohibitively expensive to revisit. The database (http://maps.dggs.alaska.gov/photodb/) includes a variety of images such as field photos, photos of samples, and photomicrographs (photograph of a microscopic object) taken with the aid of a microscope.
