Habitat Suitability Index Models: Pileated woodpecker
Richard L. Schroeder
1983, FWS/OBS 82/10.39
A review and synthesis of existing information was used to develop a habitat model for the pileated woodpecker (Dryocopus pileatus). The model is scaled to produce an index of habitat suitability between 0 (unsuitable habitat) and 1 (optimally suitable habitat) for areas of the continental United States. Habitat suitability indexes are designed for use.with...
Availability of water from the Outwash Aquifer, Marion County, Indiana
B.S. Smith
1983, Water-Resources Investigations Report 83-4144
The outwash aquifer in Marion County, Indiana is a continuous, unconfined sand and gravel deposit containing isolated boulder, till, silt, and clay deposits along the White River, Fall Creek, and Eagle Creek. Flow in the aquifer is from the boundaries of the aquifer with the Tipton till plain toward the...
Oxygen and strontium isotopic studies of basaltic lavas from the Snake River plain, Idaho
William P. Leeman, Joseph F. Whelan
1983, Open-File Report 83-338
The Snake Creek-Williams Canyon pluton of the southern Snake Range crops out over an area of about 30 km2, about 60 km southeast of Ely, Nev. This Jurassic intrusion displays large and systematic chemical and mineralogical zonation over a horizontal distance of 5 km. Major-element variations compare closely with Dalyls...
Biostratigraphic correlation chart of some Upper Cretaceous rocks from the Lost Soldier area, Wyoming to west of Craig, Colorado
J.W. Bader, J. R. Gill, W. A. Cobban, B. E. Law
1983, Miscellaneous Field Studies Map 1548
This chart depicts the time-stratigraphic relations of some Upper Cretaceous rocks along the eastern and southeastern margins of the Greater Green River Basin, south-central Wyoming and northwestern Colorado. The purpose of this report is to release a preferred set of correlations based upon marine mollusk biostratigraphy. The senior author, with...

References to more than 550 reports, articles, and maps are listed alphabetically by author and are indexed by subject. The subject index includes geographic-area terms. Citations from 69 series are included; series are listed separately. The publications listed report the results of U.S. Geological Survey research and field projects throughout...
Mineral resource assessment of the Iron River 1° x 2° quadrangle, Michigan and Wisconsin
William F. Cannon
1983, Circular 887
The Iron River 1? x 2? quadrangle contains identified resources of copper and iron. Copper-rich shale beds in the north part of the quadrangle contain 12.2 billion pounds (5.5 billion kilograms) of copper in well-studied deposits including 9.2 billion pounds (4.2 billion kilograms) that are economically minable by 1980 standards....
The Alaska Mineral Resource Assessment Program: Background information to accompany folio of geologic and mineral resource maps of the Ambler River quadrangle, Alaska
Charles F. Mayfield, I.L. Tailleur, N. R. Albert, Inyo Ellersieck, Donald Grybeck, S. W. Hackett
1983, Circular 793
The Ambler River quadrangle, consisting of 14,290 km2 (5,520 mi2) in northwest Alaska, was investigated by an interdisciplinary research team for the purpose of assessing the mineral resource potential of the quadrangle. This report provides background information for a folio of maps on the geology, reconnaissance geochemistry, aeromagnetics, Landsat imagery,...
Reconnaissance geology of the Ghazzalah Quadrangle, sheet 26/41 A, Kingdom of Saudi Arabia
James E. Quick
1983, Open-File Report 83-331
The Ghazzalah quadrangle is located in the northern Precambrian shield of Saudi Arabia between lat 26?30' and 27?00' N. and long 41?00' and 41?30' E. The area is underlain by two lithologically distinct, Precambrian volcanosedimentary units and a wide range of dioritoid and granitoid plutonic intrusive rocks. The only Phanerozoic...
Density, porosity, and magnetic properties of rock specimens from southwestern Arizona
Douglas P. Klein, Gordon R. Johnson
1983, Open-File Report 83-808
Petrophysical data on 364 rock specimens from southwest Arizona are tabulated and summarized by major rock suites for that part of southwest Arizona covered by the Ajo 1? x 2? quadrangle and the Papago Indian Reservation. Data for 202 of these specimens are new and previously unreported. The tabulation also...
