Correlation of the Klamath Mountains and Sierra Nevada Correlation of the Klamath Mountains and Sierra Nevada
This report graphically portrays the broadly parallel tectonic development of the Klamath Mountains and Sierra Nevada from early Paleozoic to Early Cretaceous time. It is dedicated to J.S. Diller of the U.S. Geological Survey who, during his pioneer field studies a century ago, recognized significant similarities between these two important provinces. The report is based mainly on the...

Modeling precipitation and sorption of elements during mixing of river water and porewater in the Coeur d'Alene River basin Modeling precipitation and sorption of elements during mixing of river water and porewater in the Coeur d'Alene River basin
Reddish brown flocs form along the edge of the Coeur d'Alene River when porewater drains into river water during the annual lowering of water level in the basin. The precipitates are efficient scavengers of dissolved elements and have characteristics that may make metals associated with them bioavailable. This work characterizes the geochemistry of the porewater and models the formation...

Importance of Sediment-Water Interactions in Coeur d'Alene Lake, Idaho, USA: Management Implications Importance of Sediment-Water Interactions in Coeur d'Alene Lake, Idaho, USA: Management Implications
A field study at Coeur d'Alene Lake, Idaho, USA, was conducted between October 1998 and August 2001 to examine the potential importance of sediment-water interactions on contaminant transport and to provide the first direct measurements of the benthic flux of dissolved solutes of environmental concern in this lake. Because of potential ecological effects, dissolved zinc and...

Studies by the U.S. Geological Survey in Alaska, 2001 Studies by the U.S. Geological Survey in Alaska, 2001
The collection of 14 studies that follow continues the series of U.S. Geological Survey (USGS) investigative reports in Alaska under the broad umbrella of the geologic sciences. This series presents new and sometimes-preliminary findings that are of interest to Earth scientists in academia, government, and industry; to land and resource managers; and to the general public. The reports...

Surficial and bedrock geologic map database of the Kelso 7.5 Minute quadrangle, San Bernardino County, California Surficial and bedrock geologic map database of the Kelso 7.5 Minute quadrangle, San Bernardino County, California
This geologic map database describes geologic materials for the Kelso 7.5 Minute Quadrangle, San Bernardino County, California. The area lies in eastern Mojave Desert of California, within the Mojave National Preserve (a unit of the National Parks system). Geologic deposits in the area consist of Proterozoic metamorphic rocks, Cambrian-Neoproterozoic sedimentary rocks, Mesozoic plutonic...

Isotopes and ages in the northern Peninsular Ranges batholith, southern California Isotopes and ages in the northern Peninsular Ranges batholith, southern California
Strontium, oxygen and lead isotopic and rubidium-strontium geochronologic studies have been completed on Cretaceous and Jurassic (?) granitic rock samples from the northern Peninsular Ranges batholith in southern California. Many of these samples were collected systematically and studied chemically by A. K. Baird and colleagues (Baird and others, 1979). The distribution of these granitic...

Preliminary geologic map of the Fontana 7.5' quadrangle, Riverside and San Bernardino Counties, California Preliminary geologic map of the Fontana 7.5' quadrangle, Riverside and San Bernardino Counties, California
Open-File Report 03-418 is a digital geologic data set that maps and describes the geology of the Fontana 7.5’ quadrangle, Riverside and San Bernardino Counties, California. The Fontana quadrangle database is one of several 7.5’ quadrangle databases that are being produced by the Southern California Areal Mapping Project (SCAMP). These maps and databases are, in turn, part of the nation...

Intrusive rock database for the Digital Geologic Map of Utah Intrusive rock database for the Digital Geologic Map of Utah
Digital geologic maps offer the promise of rapid and powerful answers to geologic questions using Geographic Information System software (GIS). Using modern GIS and database methods, a specialized derivative map can be easily prepared. An important limitation can be shortcomings in the information provided in the database associated with the digital map, a database which is often based...
