Modeling of the Climax Stock and Related Plutons Based on the Inversion of Magnetic Data, Southwest Nevada
Geoffrey A. Phelps, Robert C. Jachens, Barry C. Moring, Carter W. Roberts
2004, Open-File Report 2004-1345
Two models of the Climax and Gold Meadows stocks were generated using a new method of magnetic inversion modeling based on the pseudogravity anomaly. The first model examined the shape of the two stocks and their connection at depth, concluding that the stocks are connected -4000 m below the ground...
Preliminary geologic map of the El Cajon 30' x 60' quadrangle, Southern California
Victoria R. Todd (compiler)
2004, Open-File Report 2004-1361
This data set maps and describes the geology of the El Cajon 30' x 60' quadrangle, southern California. Compilation of the El Cajon quadrangle is based upon published mapping at various scales, unpublished mapping at 1:24,000 scale, and reconnaissance mapping. Mapping was done by fieldwork and the use...
Springs on and in the vicinity of Mount Hood volcano, Oregon
Manuel Nathenson
2004, Open-File Report 2004-1298
Chemical and isotopic data are presented for nonthermal, thermal, and slightly thermal springs and drill holes and fumaroles on Mount Hood, Oregon. Temperatures of nonthermal springs on Mount Hood decrease with elevation and are similar to air temperatures from nearby weather stations. Dissolved constituents in nonthermal springs generally increase with...
Nutrient concentrations in Upper and Lower Echo, Fallen Leaf, Spooner, and Marlette Lakes and associated outlet streams, California and Nevada, 2002-03
Michael S. Lico
2004, Open-File Report 2004-1333
Five lakes and their outlet streams in the Lake Tahoe Basin were sampled for nutrients during 2002-03. The lakes and streams sampled included Upper Echo, Lower Echo, Fallen Leaf, Spooner, and Marlette Lakes and Echo, Taylor, and Marlette Creeks. Water samples were collected to determine seasonal and spatial concentrations of...
Lead isotopic compositions of common arsenical pesticides used in New England
Robert Ayuso, Nora Foley, Gilpin Robinson Jr., Gregory Wandless, Jeremy Dillingham
2004, Open-File Report 2004-1342
The three most important arsenical pesticides and herbicides that were extensively used on apple, blueberry, and potato crops in New England from mid-1800s to recent times are lead arsenate, calcium arsenate, and sodium arsenate. Lead arsenate was probably the most heavily used of the arsenical pesticides until it was banned...
Proceedings of the twentieth annual meeting of the Society for Organic Petrology
Linda J. Bragg, Erika E. Lentz, Peter D. Warwick, Robert B. Finkelman, Michael H. Trippi, editor(s)
2004, Open-File Report 2004-1283
The Society for Organic Petrology (TSOP; pronounced "Tee'-sop") was established in 1984 to consolidate and foster the organizational activities of scientists and engineers involved with coal petrology, kerogen petrology, organic geochemistry, and related disciplines. The following report, "Proceedings of the Twentieth Annual Meeting of The Society for Organic Petrology" (ISSN...
Rainfall, runoff, and water-quality data for the urban storm-water program in the Albuquerque, New Mexico, metropolitan area, water year 2002
Todd Kelly, Orlando Romero, Eric Turner
2004, Open-File Report 2004-1347
Urbanization has dramatically increased precipitation runoff to the system of drainage channels and natural stream channels in the Albuquerque, New Mexico, metropolitan area. Rainfall and runoff data are important for planning and designing future storm-water conveyance channels in newly developing areas. Storm-water quality also is monitored in accordance with the...
NADM Conceptual Model 1.0 -- A Conceptual Model for Geologic Map Information
North American Geologic Map Data Model (NADM) Steering Committee Data Model Design Team
2004, Open-File Report 2004-1334
Executive Summary -- The NADM Data Model Design Team was established in 1999 by the North American Geologic Map Data Model Steering Committee (NADMSC) with the purpose of drafting a geologic map data model for consideration as a standard for developing interoperable geologic map-centered databases by state, provincial, and federal...
Flood of June 4-5, 2002, in the Maquoketa River Basin, east-central Iowa
David A. Eash
2004, Open-File Report 2004-1250
Severe flooding occurred on June 4-5, 2002, in the Maquoketa River Basin in Delaware, Dubuque, Jackson, and Jones Counties, following thunderstorm activity over east-central Iowa. The rain gage at Cascade, Iowa, recorded a 14-hour rainfall of 6.0 inches at noon on June 4. Radar indications estimated as much as 8...
Hydraulic conductivity of near-surface alluvium in the vicinity of Cattlemans Detention Basin, South Lake Tahoe, California
Jena M. Green, Katherine K. Henkelman, Rachel M. Caskey
2004, Open-File Report 2004-1201
Cattlemans detention basin, South Lake Tahoe, California is designed to capture and reduce urban runoff and pollutants originating from developed areas before entering Cold Creek, which is tributary to Trout Creek and to Lake Tahoe. The effectiveness of the basin in reducing sediment and nutrient loads currently is being assessed...
VPV--The velocity profile viewer user manual
John M. Donovan
2004, Open-File Report 2004-1255
The Velocity Profile Viewer (VPV) is a tool for visualizing time series of velocity profiles developed by the U.S. Geological Survey (USGS). The USGS uses VPV to preview and present measured velocity data from acoustic Doppler current profilers and simulated velocity data from three-dimensional estuarine, river, and lake hydrodynamic models....
Lime kiln dust as a potential raw material in portland cement manufacturing
M. Michael Miller, Robert M. Callaghan
2004, Open-File Report 2004-1336
In the United States, the manufacture of portland cement involves burning in a rotary kiln a finely ground proportional mix of raw materials. The raw material mix provides the required chemical combination of calcium, silicon, aluminum, iron, and small amounts of other ingredients. The majority of calcium is supplied in...
