The chromograph, a new analytical tool for laboratory and field use
Rollin Elbert Stevens, Hubert William Lakin
1949, Circular 63
Water supplies in the Greater Atlanta Region, Georgia, are obtained mainly from surface-water sources, but there is concern that these sources may be unable to meet rising demands. This study indicates that large quantities of good-quality ground water are obtainable from selected sites in the crystalline rocks of the area....
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,...

1949, Water Supply Paper 1069
This report gives a summarized description of the public water supplies in 35 counties of central and north-central Texas, extending from the southern boundaries of Travis, Blanco, Gillespie, and Kerr Counties northward to the TexasOklahoma State line. It gives the available data as follows for each of the 145 communities:...
Ground-water supplies of the Ypsilanti area, Michigan
Charles L. McGuinness, O.F. Poindexter, E. G. Otton
1949, Water Supply Paper 1078

Geochemical prospecting for ores; a progress report
Herbert Edwin Hawkes
1949, Economic Geology (44) 706-712
Methods of prospecting for mineral deposits by means of chemical studies of residual soil, alluvium, glacial moraine, vegetation, and natural water were first applied on a systematic scale in Scandinavia and Russia about 15 years ago. Since the war, work in this field has been undertaken by several independent groups...
Ostracoda from well, shot hole, and outcrop samples in Naval Petroleum Reserve No. 4
Frederick M. Swain
1949, Geological Investigations, Naval Petroleum Reserve No. 4, Alaska 27
The ostracodes described in this report are from material collected in Naval Petroleum Reserve No. 4, northern Alaska. The samples were obtained from well and seismograph shot holes drilled by Arctic Contractors and United States Geophysical Company and from field samples collected by the United States Geological Survey in the...
The relation between earth movements and volcanism in the San Juan Mountains of Colorado
Esper S. Larsen Jr.
1949, Eos, Transactions, American Geophysical Union (30) 862-866
The late Tertiary volcanism in the San Juan Mountains of southwestern Colorado followed a long interval during which the crust was stable. The volcanic rocks have been divided into four main groups, (1) those of pre‐Potosi (?) age in the eastern area, (2) the Lake Fork quartz latite, San Juan...
Alpine glaciation

Buried preglacial ground water channels in the Albany-Schenectady area in New York
Eugene S. Simpson
1949, Economic Geology (44) 713-720
A map is presented showing contours of the buried preglacial channel of the Mohawk River from Schenectady, New York, to its confluence with the Hudson River about 12 miles south of Albany and of associated buried preglacial channels. The Pleistocene history of a portion of the Mohawk and Hudson Rivers...
Suggested correlation in Simpson seeps region
F. M. Robinson, Robert Thomas
1949, Geological Investigations, Naval Petroleum Reserve No. 4, Alaska 13
During the 1949 drilling season eight core tests were completed in the Simpson Seeps area up to October 25th„ This program, which is still in progress, was undertaken to provide an explanation for the surface seeps near Caps Simpson. The shallowest of the eight holes reached 800 feet; the deepest...
