Stratigraphic sections of the Phosphoria formation in Wyoming
V.E. McKelvey, L.E. Smith, R.A. Hoppin, F.C. Armstrong
1951, Open-File Report 51-18-D
The first of a series of reports giving detailed stratigraphic sections of the Phosphoria formation in the Western phosphate field as measured and described by the Geological Survey will be released as Circulars within the next few months. Because of the needs of industry for many of these data during...
Reconnaissance of radioactive rocks of Maine
John M. Nelson, Perry F. Narten
1951, Trace Elements Investigations 68
The state of Maine was traversed with car-mounted Geiger-Mueller equipment in the late summer of 1948 and the radioactivity of approximately 4,600 miles of road was logged. All samples were analyzed, both in the field by comparing the radioactivity of each sample to the radioactivity of a stranded measured with a...
Reconnaissance of radioactive rocks of Massachusetts
Donald H. Johnson
1951, Trace Elements Investigations 69
During the 1948 and 1949 field seasons radiometric car traverses were made along the numbered federal and state highways and along many unnumbered roads of Massachusetts. Near Worcester pegmatitic rocks are estimated to contain about 250 pounds of uranium and 8,500 pounds of thoria per foot of depth. Near Southbridge pegmatitic rocks are...
Geology of the eastern part of the Centralia - Chehalis coal district, Lewis and Thurston Counties, Washington
Parke Detweiler Snavely Jr., A. E. Roberts, Linn Hoover Jr., M. H. Pease Jr.
1951, Coal Map 8
This report gives the results of geologic investigations made in 1948 and 1949 in the eastern part of the Centralia-Chehalis coal district of southwest Washington. Detailed geologic mapping and stratigraphic studies were supplemented by core drilling. The core drilling tested the thickness and physical character of the individual coal beds...
Geology of anthracite in the east-central part of the Mount Carmel quadrangle, Pennsylvania
Howard Eugene Rothrock, Holly C. Wagner, Boyd R. Haley, Harold H. Arndt
1951, Coal Map 10
The Pennsylvania anthracite fields, the principal source of anthracite in North America, are in the eastern part of the Commonwealth of Pennsylvania. The coal occurs in four elongate areas - Northern, Western Middle, Eastern Middle, and Southern fields - that trend northeastward and lie in echelon arrangement. The fields range...
