Petrology of the Plutonic Rocks of west-central Alaska
Thomas P. Miller
1970, Open-File Report 71-210
A series of plutons in west-central Alaska defines the Hogatza plutonic belt which extends for about 200 miles in an east-west direction from the northeastern Seward Peninsula to the Koyukuk River. The plutonic rocks have an aggregate area of about 1,200 square miles and their composition, distribution, and possible petrogenesis...
Flood profile study, Morgan Creek, Linn County, Iowa
Harlan H. Schwob
1970, Open-File Report 70-295
The purpose of this report is to present the results of a study made for a 35,000-foot reach of Morgan Creek. The report shows profiles computed for a large flood under existing conditions and for a smaller flood for two assumed conditions of encroachment. Flood-plain management can benefit from this...
A strategy for the geologic exploration of the planets
M. H. Carr
1970, Circular 640
The geology of the planets bears directly on three basic aims of lunar and planetary exploration: determination of the origin and evolution of the solor system; determination of the origin and evolution of life; and clarification of the nature of the processes shaping man's terrestrial environment (National Academy of Sciences, 1966...
Preliminary description of cores, chemical analyses of lignite beds, and map showing locations of holes drilled in Grant, Hettinger, Morton, and Stark Counties, North Dakota
H.L. Smith
1970, Open-File Report 70-308
Nineteen exploratory holes were drilled in Grant, Hettinger, Morton, and Stark Counties, N. Dak. (fig. 1), for the U.S. Geological Survey from June 7 to September 15, 1966. This prospect drilling was undertaken to gather data on the thickness, quality, and extent of lignite beds and the lithologic characteristics of...
Geology of the north end of the Ruby Range, southwestern Montana
Russell G. Tysdal
1970, Open-File Report 70-333
This study consists of two parts: stratigraphy and sedimentation, and structure of rocks in the northern one-third of the Ruby Range of southwestern Montana. Detailed studies of Cambrian marine dolomite rocks in the Red Lion Formation and in the upper part of the Pilgrim Limestone resulted in their division into...
Streamflow in the upper Santa Cruz River basin, Santa Cruz and Pima Counties, Arizona
Alberto Condes de la Torre
1970, Water Supply Paper 1939-A
Streamflow records obtained in the upper Santa Cruz River basin of southern Arizona, United States, and northern Sonora, Mexico, have been analyzed to aid in the appraisal of the surface-water resources of the area. Records are available for 15 sites, and the length of record ranges from 60 years for...
Geologic evaluation of 3-5 micrometer infrared imagery and color photography in southern Utah
Robert J. Hackman, Paul L. Williams
1970, Open-File Report 71-140
A comparison of 3-5 micrometer, afternoon and midnight infrared (IR) imagery and color photography with conventional aerial photography shows that IR imagery and color photography have some unique capabilities. In general, the IR imagery provides in shades of gray a record of the relative ground temperature at the time the...
