This collection contains unpublished hand drawn geologic maps, field maps, traverse maps, sample location maps, and cross sections of Traveler Mountain and vicinity, central Maine. The maps were created by Douglas W. Rankin between 1955 and 1961 (date is indicated if known) and scanned in 2016. Most maps use a 7.5-minute topographic quadrangle as a base. Some compiled maps of larger areas are a composite of several 7.5-minute quadrangle maps and latitude and longitude values are indicated on the map. Please contact the Eastern Geology and Paleoclimate Science Center for additional information and access to original copies.

The US Geological Survey, in cooperation with the National Park Service, mapped 35 7.5-minute quadrangles, within a 2-mile-wide+ corridor centered on the Parkway, from BLRI (Blue Ridge Parkway) Mile Post (MP) 0 near Afton, Virginia southward to MP 218 at Cumberland Knob, approximately 1.3 km south of the Virginia – North Carolina State Line. Detailed bedrock geologic mapping for this project was conducted at 1:24,000-scale by systematically traversing roads, trails, creeks, and ridges within and adjacent to the 2-mile-wide+ corridor along the 216.9-mile length of the BLRI in Virginia. Geologic data at more than 23,000 station points were collected during this project (September 2009 – February 2014), with approximately...

Afghanistan is endowed with a broad range of mineral resources. Currently, the majority of mining throughout the country is comprised of informal and undocumented artisanal and small-scale mining (ASM) operations. The exact scope of excavation operations depends largely on the mineral commodity produced. In the case of gemstones, such as emeralds and rubies, small teams of miners use manual equipment such as pick-axes, shovels, and explosives to blast the host rock to access the minerals. Other mineral commodities like talc, coal, and chromite, as well as development minerals such as construction stone, sand, and gravel, are extracted using larger, semi-industrial methods. These operations are often well-organized,...

Iron oxide-apatite (IOA) deposits of the Adirondack Mountains of New York locally contain elevated rare earth element (REE) concentrations (e.g. Taylor and others, 2019). Critical to evaluating resource potential is understanding the genesis of the IOA deposits that host the REE-rich minerals. As part of this effort, the U.S. Geological Survey (USGS) is conducting bedrock geologic mapping, geochronology, geochemistry, and geophysics in the region. Published and ongoing research demonstrates the spatial association of IOA deposits with the Lyon Mountain Granite Gneiss (LMG), and so understanding the relationship of the LMG to the IOA deposits is important for resource evaluation—however the age and origin of the...

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
