Preliminary results of induced polarization-resistivity surveys in the Northgate district, Colorado
Gordon Robert Francis Johnson
1971, Open-File Report 71-159
Induced polarization (I.P.) and resistivity surveys were made at selected locations in the Northgate district, Jackson County, Colorado. The objectives of the study were (1) to determine the feasibility of detecting and delineating pyrite-altered zones adjacent to fluorsparmineralized veins, and (2) to locate buried or obscured extensions of these fluorspar...
Application of borehole geophysics to water-resources investigations
W.S. Keys, L.M. MacCary
1971, Techniques of Water-Resources Investigations 02-E1
This manual is intended to be a guide for hydrologists using borehole geophysics in ground-water studies. The emphasis is on the application and interpretation of geophysical well logs, and not on the operation of a logger. It describes in detail those logging techniques that have been utilized within the Water...
Determination of minor elements in water by emission spectroscopy
Paul R. Barnett, E. C. Mallory
1971, Techniques of Water-Resources Investigations 05-A2
With the emission spectrograph, the analyst is able to determine many minor elements simultaneously in water samples. Spectrographic methods differ chiefly in techniques of preconcentrating the elements. For waters with dissolved solids of less than 1,000 milligrams per liter, the method of evaporating to dryness and determining the elements in...
Combined Ice and Water Balances of Gulkana and Wolverine Glaciers, Alaska, and South Cascade Glacier, Washington, 1965 and 1966 Hydrologic Years
Mark Frederick Meier, Wendell V. Tangborn, Lawrence R. Mayo, Austin Post
1971, Professional Paper 715-A
Glaciers occur in northwestern North America between lat 37 deg and 69 deg N. in two major mountain systems. The Pacific Mountain System, near the west coast, receives large amounts of precipitation, has very mild temperatures, and contains perhaps 90 percent of the glacier ice. The Rocky Mountain or Eastern...
Geologic map of the Bonpland PQC region of the Moon
S.R. Titley
1971, IMAP 678
This geologic map has been prepared from the photographic data returned by Ranger VII and is one of a series prepared from the data returned by the Ranger VII, VIII, and IX spacecraft. The map area, in Mare Cognitum, includes the Ranger VII impact point. The map shows the...
