Hydrologic conditions in the Florida Panther National Wildlife Refuge, 2006-2007
Ronald S. Reese
2010, Open-File Report 2010-1270
Much of the surface water that flows into the Florida Panther National Wildlife Refuge (FPNWR) probably exits southward through Fakahatchee Strand as it did prior to development, because culverts and bridges constructed along I-75 allow overland flow to continue southward within the strand. During the dry season and periods of...

Bruce G. Campbell, Alissa L. Coes
2010, Professional Paper 1773
The Atlantic Coastal Plain aquifers and confining units of North and South Carolina are composed of crystalline carbonate rocks, sand, clay, silt, and gravel and contain large volumes of high-quality groundwater. The aquifers have a long history of use dating back to the earliest days of European settlement in the...

William E. Wilson
2010, Circular 1362
The decade of the 1870s was a time of extensive exploration and surveying in the American West. The nation needed knowledge of the cultural features, topography, natural resources, and geology of this land to promote and aid the 'rapid development of an empire.' The need was particularly acute in the...

A. Greene, Michael O. Garcia, Dominique Weis, Garrett Ito, Maia Kuga, Joel Robinson, Seiko Yamasaki
2010, Geochemistry, Geophysics, Geosystems (11)
The longest distance between subaerial shield volcanoes in the Hawaiian Islands is between the islands of Kaua‘i and O‘ahu, where a field of submarine volcanic cones formed astride the axis of the Hawaiian chain during a period of low magma productivity. The submarine volcanoes lie ∼25–30 km west of Ka‘ena...

Historical files from Federal government mineral exploration-assistance programs, 1950 to 1974
David G. Frank
2010, Fact Sheet 2010-3109
Congress enacted the Defense Production Act in 1950 to provide funding and support for the exploration and development of critical mineral resources. From 1950 to 1974, three Department of the Interior agencies carried out this mission. Contracts with mine owners provided financial assistance for mineral exploration on a joint-participation basis....
Approaches to highly parameterized inversion-A guide to using PEST for groundwater-model calibration
John E. Doherty, Randall J. Hunt
2010, Scientific Investigations Report 2010-5169
Highly parameterized groundwater models can create calibration difficulties. Regularized inversion-the combined use of large numbers of parameters with mathematical approaches for stable parameter estimation-is becoming a common approach to address these difficulties and enhance the transfer of information contained in field measurements to parameters used to model that system. Though...
Estimating Monthly Water Withdrawals, Return Flow, and Consumptive Use in the Great Lakes Basin
Kimberly H. Shaffer, Rosemary S. Stenback
2010, Open-File Report 2010-1211
Water-resource managers and planners require water-withdrawal, return-flow, and consumptive-use data to understand how anthropogenic (human) water use affects the hydrologic system. Water models like MODFLOW and GSFLOW use calculations and input values (including water-withdrawal and return flow data) to simulate and predict the effects of water use on aquifer and...
Identification of tsunami deposits in the geologic record; developing criteria using recent tsunami deposits
Robert Peters, Bruce Jaffe
2010, Open-File Report 2010-1239
There is a need for a clear procedure to identify tsunami deposits in the geologic record. Data from published studies documenting recent tsunami deposits provide a means of developing identification criteria based on the sedimentary characteristics of unequivocal tsunami deposits. Recent tsunami deposits have many sedimentary characteristics in common. All...
The role of water in generating the calc-alkaline trend: New volatile data for aleutian magmas and a new tholeiitic index
Mindy M. Zimmer, Terry Plank, Erik H. Hauri, Gene Yogodzinski, Peter L. Stelling, Jessica Larsen, Brad Singer, Brian R. Jicha, Charlie Mandeville, Christopher J. Nye
2010, Journal of Petrology (51) 2411-2444
The origin of tholeiitic (TH) versus calc-alkaline (CA) magmatic trends has long been debated. Part of the problem stems from the lack of a quantitative measure for the way in which a magma evolves. Recognizing that the salient feature in many TH–CA discrimination diagrams is enrichment in Fe during magma...

The principal rare earth elements deposits of the United States: A summary of domestic deposits and a global perspective
Keith R. Long, Bradley S. Van Gosen, Nora K. Foley, Daniel Cordier
2010, Scientific Investigations Report 2010-5220
The rare earth elements (REE) are fifteen elements with atomic numbers 57 through 71, from lanthanum to lutetium ('lanthanides'), plus yttrium (39), which is chemically similar to the lanthanide elements and thus typically included with the rare earth elements. Although industrial demand for these elements is relatively small in tonnage...
