Intrusive rocks of the Holden and Lucerne quadrangles, Washington— The relation of depth zones, composition, textures, and emplacement of plutons
Fred W. Cater
1982, Professional Paper 1220
The core of the northern Cascade Range in Washington consists of Precambrian and upper Paleozoic metamorphic rocks cut by numerous plutons, ranging in age from early Triassic to Miocene. The older plutons have been eroded to catazonal depths, whereas subvolcanic rocks are exposed in the youngest plutons. The Holden and...
Reconnaissance of stream biota and physical and chemical water quality in areas of selected land use in the coal-mining region, southwestern Indiana, 1979-80
D. J. Wangsness
1982, Open-File Report 82-566
To help meet the goals of the Surface-Mining Control and Reclamation Act of 1977, the U.S. Geological Survey is assessing the physical, chemical, and biological characteristics of surface water within the coal-mining region of southwestern Indiana. This report discusses benthic-invertebrate and periphyticalgal communities in streams draining homogeneous-agricultural, forested, active/reclaimed-mine, reclaimed-mine,...

Use of a three-dimensional model for the analysis of the ground-water flow system in Parker Valley, Arizona and California
Patrick Tucci
1982, Open-File Report 82-1006
A three-dimensional, finite-difference model was used to simulate ground-water flow conditions in Parker Valley. The study evaluated present knowledge and concepts of the ground-water system and the ability of the model to represent the system. Modeling assumptions and generalized physical parameters that were used may have transfer value in the...

Hydrology of the Floridan Aquifer in Northwest Volusia County, Florida
A. T. Rutledge
1982, Open-File Report 82-108
Northwest Volusia County, in east-central Florida, is a 262-square-mile area including the southern part of the Crescent City Ridge and the northern tip of the DeLand Ridge. The hydrogeologic units in the area include the Floridan aquifer, which is made up of parts of the Lake City Limestone, the Avon...
Chemical quality of water in the upper part of the Floridan aquifer, Duval County, Florida
Thomas H. Thompson
1982, Open-File Report 82-119
The Floridan aquifer is the principle source of freshwater in Duval County (fig. 1). Most water-supply wells penetrate only the upper 600 feet of the aquifer because highly mineralized water is found in the deeper zone. Earlier investigations have shown that within the upper 600 feet of the aquifer, the...

Saturated thickness of the High Plains regional aquifer in 1980, northwestern Oklahoma
John S. Havens
1982, Open-File Report 82-760
During 1978, the U.S. Geological Survey began a 5-year study of the High Plains regional aquifer system to provide hydrologic information for evaluation of the effects of long-term development of the aquifer and to develop computer models for prediction of aquifer response to alternative changes in ground-water management (Weeks, 1978)....
