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...
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 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...

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...
