Artesian water in Somervell County, Texas
Albert George Fiedler
1934, Water Supply Paper 660
Somervell County is part of the Grand Prairie region of north-central Texas. An excellent supply of artesian water is available from the Trinity reservoir at no great depth. The first flowing well in Somervell County was drilled in 1880, and the first flowing well in Glen Rose, the county seat,...
Gold-quartz veins south of Libby, Montana
Russell Gibson
1934, Circular 7
The area described in this paper is one of rugged mountains, composed chiefly of folded and faulted sedimentary rocks of the Belt series. In the nearby region the beds are intruded by diorite sills and granitic stocks. Glacial drift, including silt deposited in a lake, covers much of the lower...
Ground-water supplies and irrigation in San Pedro Valley, Arizona
Kirk Bryan, G. E. P. Smith, Gerald A. Waring
1934, Open-File Report 67-31
The San Pedro Valley in southeastern Arizona extends from the International Boundary northward about 120 miles to the junction of the San Pedro River with the Gila River.  The river basin also extends about 75 miles into Mexico.  The valley varies in width from 5 to 20 miles, being widest...
Fifty-fifth annual report of the Director of the Geological Survey
Walter Curran Mendenhall
1934, Annual Report 55
From the point of view of the geologists of this continent, the important event of the year was the meeting in Washington, in July, of the sixteenth session of the International Geological Congress.  The only other session held in the United States was the fifth, in 1891....
Field evidence about the viscosity of lavas
Clarence S. Ross
1934, Eos, Transactions, American Geophysical Union (15) 255-257
There appears to be surprisingly little definite information on the viscosity of lavas. With few exceptions writers content themselves with such general and indefinite terms as “mobile”, “viscous”, or “highly viscous”. Apparently the only attempts to actually calculate viscosity have been made on Hawaiian lavas.  ...
The Rôle of volatiles in the formation of Virginia titanium deposits
C. S. Ross
1934, Eos, Transactions, American Geophysical Union (15) 245-245
The feldspathic rock with which the titanium deposits of Virginia are associated appears to be an anorthosite, although the plagioclase is somewhat more sodic than in normal anorthosites. That is, this rock shows evidence of having been introduced as a mush‐like mass of crystals and intersititial magma, and of undergoing...
Relation of stream‐flow to ground‐water levels
L.L. Harrold
1934, Eos, Transactions, American Geophysical Union (15) 414-416
In recent years the Water Resources Branch of the United States Geological Surrey has given considerable attention to the relation of ground‐water to stream‐flow. One locality in which this relation is being studied is about 13 miles from Washington, near Colesvllle, Maryland, where a Kinnison float‐gage is being maintained in a well In connection with the operation of a...
A study of salt‐water encroachment in the Galveston Area, Texas
Samuel F. Turner, Margaret D. Foster
1934, Eos, Transactions, American Geophysical Union (15) 432-435
A survey of the ground‐water resources of the region in which Houston and Galveston are situated was started in December 1930 by the United States Geological Survey in cooperation with the Texas Board of Water Engineers. In connection with this survey a special study is being made of the geochemical relations of the ground‐waters of an area about 25 miles wide and 90 miles long, extending from Galveston northwestward through Houston. This study considers the influence...
