Mineral investigations between Khamis Mushayt and Bi'r Idimah, Saudi Arabia
William C. Overstreet, U.S. Geological Survey Saudi Arabian Project
1968, Open-File Report 68-208
Mineral investigations between Khamis Mushayt and Bi'r Idimah in the Asir quadrangle, sheet 1-217 (Brown and Jackson, 1959) began September 24, 1964 and ended November 20. Total distance travelled was 6264 kilometers. Sixteen camps were set, and 483 samples of various geologic materials, principally wadi sands, laterite, and gossan, were...
Streamflow generalization in an area of the central United States
I. C. James II
1968, Open-File Report 68-145
Streamflow records of a sample of 41 natural flow stations in an area of the Central Plains were analyzed by electronic computer for the statistics of annual high-flow and low-flow volumes, flow duration, and monthly- and annual-flow discharges. Peak discharges and high- and low-flow volumes for different durations were computed...
Monthly surface-water inflow to Chesapeake Bay
Conrad D. Bue
1968, Open-File Report 68-29
This report presents a convenient and rapid means of estimating, on either a monthly or a yearly basis, the inflow from surface streams to Chesapeake Bay. The method was developed as a working base for the release entitled "Estimated stream discharge entering Chesapeake Bay" prepared by the U. S. Geological...
Geologic interpretation of reconnaissance aeromagnetic survey of northeastern Alaska
W. P. Brosge, E. E. Brabb, E. R. King
1968, Open-File Report 68-23
Aeromagnetic surveys of Naval Petroleum Reserve No. 4 (Woolson and others, 1962) and of a 900-square-mile area near Fairbands (Andreasen and others, 1964) are the only published aeromagnetic reports on northeastern Alaska.Several total intensity aeromagnetic profiles, primarily over the Yukon Flats in the central part of the area shown on...
Reconnaissance geology, mineral occurrences, and geochemical anomalies of the Yentna district, Alaska
Allen L. Clark, C. C. Hawley
1968, Open-File Report 68-35
The Yentna district, in south-central Alaska, is underlain by slightly metamorphosed Mesozoic sedimentary rocks, and by sandstones, conglomerates and coaly minerals of the Tertiary Kenai Formation. The bedrock is locally covered by extensive surficial deposits of Quaternary and Recent (Holocene) age. The Mesozoic strata are cut by a quartz monzonite...
