Placer deposits of Alaska
Edward Huntington Cobb
1972, Open-File Report 72-71
Placer deposits, in addition to their intrinsic value, serve as indicators of areas of potential development of lode deposits. Any possibility that Alaska may again become an important source of metallic mineral commodities depends in part on an inventory of placer deposits and a knowledge of the geology of their...
Tectonic map of Liberia based on geophysical and geological surveys
John Charles Behrendt, Cletus S. Wotorson
1972, Open-File Report 72-32
Interpretation of the results of aeromagnetic, total-gamma radioactivity, and gravity surveys combined with geologic data for Western Liberia from White and Leo (1969) and other geologic information allows the construction of a tectonic map of Liberia. The map approximately delineates the boundaries between the Liberian (ca. 2700 m.y.) province in...
Geological and geophysical investigations of an Apollo 9 photo anomaly near Point of Pines, Arizona
Calvin S. Bromfield, G. P. Eaton, D. L. Peterson, J.C. Ratte
1972, Open-File Report 72-51
An infrared photograph of southeastern Arizona, taken during the Apollo 9 multispectral terrain photography experiment in 1969, reveals a ringlike feature, some 3-4 miles (5-6 kin) in diameter, on the Natanes Plateau, 35 miles (56 kin) north of the town of Safford. Because the feature occurs in an area of...
Bartin-Amasra earthquake, Turkey, September 3, 1968
John Patrick Albers, Adnan Kalifatcioglu
1972, Open-File Report 72-3
A brief examination of the Bartin-were whether earthquake area was made on September 23 and September 24,1968, by the authors to determine whether or not geologic effects had been produced that were significant enough to warrant further detailed study by the Mineral Research and Exploration Institute of Turkey or by...
Metal provinces of Alaska
Allen L. Clark, H. C. Berg, E.H. Cobb, G.D. Eberlein, E.M. MacKevett Jr., T. P. Miller
1972, Open-File Report 72-69
Computation of fluvial-sediment discharge
George Porterfield
1972, Techniques of Water-Resources Investigations 03-C3
This report is one of a series concerning the concepts, measurement, laboratory procedures, and computation of fluvial-sediment discharge. Material in this report includes procedures and forms used to compile and evaluate particle-size and concentration data, to compute fluvial-sediment discharge, and to prepare sediment records for publication....
Low-flow investigations
H. C. Riggs
1972, Techniques of Water-Resources Investigations 04-B1
This manual describes methods of defining the low-flow characteristics of streams, shows how certain basin characteristics influence the mean and variability of annual low flows, and recommends procedures for data collection, analysis, and reporting....
Appraisal of stream sedimentation in the Susquehanna River basin
Kenneth F. Williams, Lloyd A. Reed
1972, Water Supply Paper 1532-F
The Susquehanna River presently transports about 3.0 million tons of sediment annually (110 tons per square mile). Only about 1.8 million tons of sediment enters the head of Chesapeake Bay annually because some sediment is trapped behind the power dams on the lower Susquehanna. Measured annual sediment yields from subbasins...
