G. E. Andreasen, M. F. Kane, I. Zietz
1962, Geophysics (27) 343-358
A contour map of the Precambrian surface for a part of northeastern New Mexico has been prepared from aeromagnetic, gravity, and drill-hole data. The area extends approximately from the Colorado border south to latitude34° N., and from the foothills of the Sangre de Cristo Mountains east to longitude 104° W. Thirty-seven...
Paleozoic seas of central Idaho
Clyde P. Ross
1962, Geological Society of America Bulletin (73) 769-793
Some recent paleogeographic maps indicate that central Idaho was part of a major geosyncline throughout Paleozoic time. This concept, apparently based on thick marine accumulations far apart on the margins of the region, is inconsistent with field data. Within the area of the Idaho batholith, Permian(?) volcanic rocks rest either on batholithic rocks...
Magnetic anomalies and magnetizations of the Biwabik iron-formation, Mesabi area, Minnesota
G. D. Bath
1962, Geophysics (27) 627-650
In a study of the relationship of magnetic anomalies to the magnetite content and structure of layered Precambrian iron-formations, the effective induced and remanent magnetizations of the Biwabik iron-formation were determined by analyses of aeromagnetic anomalies recorded 1,000 ft above the Biwabik in areas of known geology. The induced magnetization along the layers is relatively insignificant...
Lava tree molds of the September 1961 eruption, Kilauea Volcano, Hawaii
James G. Moore, D.H. Richter
1962, GSA Bulletin (73) 1153-1158
Well-developed lava tree molds were formed during the September 1961 eruption along the east rift zone of Kilauea Volcano. The upright molds were produced where fluid lava, flowing through dense tropical forest, became chilled against the larger trees and tree ferns and later drained away. Where the lava ponded temporarily...

The potassium and sodium content of chemically analysed Cenozoic igneous rocks from about 150 areas of the western United States has been examined. For each area a plot of the molecular proportion K2O(K2O + Na2O)">K2O(K2O + Na2O) [Niggli's k-value] is shown, and the projected k-value determined at 50...
Water and the arid zone of the United States
Luna Bergere Leopold
1962, Conference Paper
In a pluvial period associated with Wisconsin glaciation the closed basin of the Estancia Valley in New Mexico held a lake which, at its maximum extent, was 150 feet deep and had a surface area of 450 square miles. This basin, with a mean elevation of about 6,000 feet, has...
A preliminary study of the distribution of saline water in the bedrock aquifers of eastern Wisconsin
Roy W. Ryling
1961, Wisconsin Geological & Natural History Survey Information Circular 5
The occurrence of saline water in the bedrock aquifers of eastern Wisconsin has been known for many years. Because of the ready availability of fresh water from other sources, little has been known of the extent of the saline-water area. Saline ground water is a potential source of contamination to...

Thomas R. LaFehr
1961, Open-File Report 62-74
A regional gravity survey in the eastern Snake River Plain was conducted in the early summer of 1961. Seven hundred and seven gravity stations were established between latitudes 42°15'N and 44°30'N between longitudes 111°30'W and 114°30'W. Three hundred and twenty-five of these stations were located in 2,700 square miles of...

1961, Bulletin 1082-J
The Carlile quadrangle-is along the northwestern flank of the Black Hills uplift in Crook County, Wyo.

Availability of ground water in the Gallup area, New Mexico
Samuel Wilson West
1961, Circular 443
A thick succession of sedimentary rocks (about 6,000 feet) underlies the town of Gallup and crops out nearby.

M. F. Kane, L.C. Pakisek
1961, Geophysics (26) 12-26
Gravity and seismic measurements in southern Owens Valley, California, have outlined a deep subsurface trough, bounded throughout the greater part of its length by steep faults.

Reconnaissance study of quaternary faults in and south of Yellowstone National Park, Wyoming
D. Love
1961, Geological Society of America Bulletin (72) 1749-1764
Normal faults offset a bedrock surface scoured by Pleistocene ice in several areas within and south of Yellowstone National Park. Recurrent earthquake shocks and fresh appearance of some scarps suggest that movement is continuing along some faults. Four systems of faults are described. Quaternary movement occurred along more than 60 faults on the Mirror Plateau, 15...

Richard L. Konizeski
1961, Geological Society of America Bulletin (72) 1633-1642
Douglass Creek basin lies west of the Continental Divide in the northern part of the Rocky Mountain physiographic province.
