BackgroundClimate change refugia, areas buffered from climate change relative to their surroundings, are of increasing interest as natural resource managers seek to prioritize climate adaptation actions. However, evidence that refugia buffer the effects of anthropogenic climate change is largely missing.MethodsFocusing on the climate-sensitive Belding’s ground squirrel...

Patrick Nadoll, Jeffrey L. Mauk, Timothy Hayes, Alan Koenig, Stephen E. Box
2017, European Journal of Mineralogy (29) 795-805
The distribution and partitioning of elements in igneous rocks is well established for various melt –(fluid) –solid pairs and provides important insights into the petrogenesis of these rocks. Studies of the partitioning behavior of elements under metamorphic conditions are scarce and commonly focus on high-grade metamorphic facies. Little is...

Richard G. Stanley, John A. Barron, Charles L. Powell II
2017, Scientific Investigations Report 2017-5125
We used geological field studies and diatom biostratigraphy to test a published hypothesis that Neogene marine siliceous strata in the Maricopa and Parkfield areas, located on opposite sides of the San Andreas Fault, were formerly contiguous and then were displaced by about 80–130 kilometers (km) of right-lateral slip along the...

2017, Data Series 1064
Earthquake-triggered ground failure, such as landsliding and liquefaction, can contribute significantly to losses, but our current ability to accurately include them in earthquake-hazard analyses is limited. The development of robust and widely applicable models requires access to numerous inventories of ground failures triggered by earthquakes that span a broad range...

Susan M. Hall, Mark J. Mihalasky, Bradley S. Van Gosen
2017, Fact Sheet 2017-3078
The U.S. Geological Survey estimates a mean of 40 million pounds of in-place uranium oxide (U3O8) remaining as potential undiscovered resources in the Southern High Plains region of Texas, New Mexico, and Oklahoma.

Community distance sampling models allowing for imperfect detection and temporary emigration
Yuichi Yamaura, J. Andrew Royle
2017, Ecosphere (8) 1-15
Recent developments of community abundance models (CAMs) enable us to analyze communities subject to imperfect detection. However, existing CAMs assume spatial closure, that is, that individuals are always present in the sampling plots, which is often violated in field surveys. Violation of this assumption, such as in the presence of...

W. Miles, Richard W. Saltus, Nathan Hayward, D. Oneschuk
2017, Open File 7862
This map is a compilation of aeromagnetic surveys over Yukon and eastern Alaska. Aeromagnetic surveys measure the total intensity of the earth's magnetic field. The field was measured by a magnetometer aboard an aircraft flown in parallel lines spaced at 200 m to 10000 m across the map area. The...
Visualization of groundwater withdrawals
Richard B. Winston, Daniel J. Goode
2017, Open-File Report 2017-1137
Generating an informative display of groundwater withdrawals can sometimes be difficult because the symbols for closely spaced wells can overlap. An alternative method for displaying groundwater withdrawals is to generate a “footprint” of the withdrawals. WellFootprint version 1.0 implements the Footprint algorithm with two optional variations that can speed up...

Vanadium is used primarily in the production of steel alloys; as a catalyst for the chemical industry; in the making of ceramics, glasses, and pigments; and in vanadium redox-flow batteries (VRBs) for large-scale storage of electricity. World vanadium resources in 2012 were estimated to be 63 million metric tons, which...
Environmental considerations related to mining of nonfuel minerals
Robert R. Seal II, Nadine M. Piatak, Bryn E. Kimball, Jane M. Hammarstrom
Klaus J. Schulz, DeYoung Jr., Robert R. Seal, II, Dwight Bradley, editor(s)
2017, Professional Paper 1802-B
Throughout most of human history, environmental stewardship during mining has not been a priority partly because of the lack of applicable laws and regulations and partly because of ignorance about the effects that mining can have on the environment. In the United States, the National Environmental Policy Act of 1969,...
