Preliminary report on selected sections of Lisburne Limestone, Brooks Range, Alaska
William P. Brosge, Hillard N. Reiser
1950, Geological Investigations, Naval Petroleum Reserve No. 4, Alaska 31
Location: - This report describes sections of the Lisburne limestone studied in the foothills and northern mountains of the Brooks Range, Alaska. The area covered extends along the front of the range from Sagavanirktok Lake (68°28' N. - 149°25' W.) west to the head of the Kukpowruk River (68°25' N....
Discussion of “Annual floods and the partial duration flood series”
Ven Te Chow, W. B. Langbein
1950, Eos, Transactions, American Geophysical Union (31) 393-941
The writer is interested in finding from this paper a similar idea which he had in mind when engaging in a statistical study of hydrologic data, a part of the Highway Drainage Research Project being carried out in the Department of Civil Engineering, the University of Illinois. However, a complete...
Activity Of Paricutin Volcano From August 1, 1948 to June 30, 1949
Carl Fries Jr., Celedonio Gutierrez
1950, Eos, Transactions, American Geophysical Union (31) 406-418
The present brief summary of activity at Paricutin Volcano, State of Michoacán, Mexico, follows the pattern of the last report on this volcano published in these Transactions late in 1948 [Wilcox and Gutierrez, 1948]. Anticipating the end of his two‐year period of observation at Parícutin in December 1948, Wilcox instructed the junior...
A preliminary report on methods of determining the age of Colorado plateau carnotite
Lorin Rollins Stieff, M.N. Girhard, T. W. Stern
1950, Trace Elements Investigations 108
Four methods of dating Colorado Plateau carnotite have been examined and evaluated: mineralogic methods, radioactive-equilibrium methods, lead-uranium-ratio methods, and lead-isotope methods. The data on 12 high-grade samples, from a suite of 50 representative carnotite ores, are presented....
Canada geese of the Mississippi flyway with special reference to an Illinois flock
Harold C. Hanson, Robert H. Smith
1950, Bulletin of the Illinois Natural History Survey (25) 67-210
This Canada goose study is based on data from three primary sources : data collected at Horseshoe Lake, Alexander County, Illinois ; surveys by the authors on the distribution, habitat, and behavior of the population elsewhere in the Mississippi flyway ; and banding records of the Jack Miner Bird Sanctuary,...
Geologic interpretation of seismic data relocation Route 1, cut, Stations 34-52, Copper Mine Road area and northern portion of Ballard Estate in Topsfield, Mass.
James E. May, Daniel Linehan
1950, Open-File Report 50-46-B
Relocation of the Newburyport Turnpike, Route 1, in Topsfield, Mass., will require a long relatively deep cut between stations 34 and 52. In order to obtain preliminary information on the depths to bedrock and on the nature of the subsurface materials at this site, reconnaissance seismic work was performed in...
Geologic interpretation of seismic data relocation Route 2, Littleton Road grade separation stations 243-252 in Harvard, Mass.
James E. May, Daniel Linehan
1950, Open-File Report 50-46-A
During parts of June and July 1949 nine seismic traverses were made at this site. Upon preliminary office development, the velocity data for some of these traverses were though to be inadequate and it was recommended that these lines be re-surveyed. Later surveys (March 1950), however, of nearby sites indicated...
Geologic interpretations of seismic data relocation Routes 15 and 20 in Sturbridge, Mass.
James E. May, Daniel Linehan
1950, Open-File Report 50-43-D
The proposed improvements at the junction of Routes 15 and 20, Sturbridge, Massachusetts, requires a cut of considerable magnitude for the relocation of east-bound Route 20 between stations 158 and 167. Geologic and seismic studies were made of the site for the purpose of determining the position of the bedrock...
Geologic interpretations of seismic data Route 128 (Northern Circumferential Highway) cut, and Hopkins Street grade separation stations 1-18 in Wakefield, Mass.
James E. May, Daniel Lineham
1950, Open-File Report 50-43-A
The completion of a segment of the Northern Circumferential Highway, Route 126, in Wakefield, Mass., requires an underpass bridge at Hopkins Street, Station 5+50. The plan of the project shows approximately 1800 feet if approach cuts between stations 1 and 18. In October 1945 a preliminary seismic study was made...
Petrology and habit of some diabase sheets in southeastern Pennsylvania
Preston Enslow Holtz
1949, Open-File Report 49-33
Small masses of granophyre occur in the upper part of diabase intrusions southeastern Pennsylvania. Diamond drill hole exploration of magnetite deposits near Dillsburg revealed a body of diabase beneath the sedimentary rocks in which the deposits occur. The drill core revealed a complete gradational sequence downward from a diabase chill...
Progress report on the geology and ground-water hydrology of the lower Platte River Valley, Nebraska, with a section on the chemical quality of the ground water
Herbert A. Waite, Herbert A. Swenson
1949, Circular 20
The occurrence of abundant ground-water supplies in the lower Platte River Valley has made possible the present agricultural and industrial economy of the area. Likewise, the future development of the area is dependent on the wise use of this important resource. The current investigation, on which this report is based,...
Interpreting ground conditions from geologic maps
Water Resources Division, U.S. Geological Survey
1949, Circular 46
Intelligent planning for heavy construction, water supply, or other land utilization requires advance knowledge of ground conditions in the area. It is essential to know:the topography, that is, the configuration of the land surface;the geology and soils, that is, the deposits that compose the land and its weathered surface; andthe...
