Flowage and recrystallization in paleozoic quartzites
Robert E. Fellows
1943, Eos, Transactions, American Geophysical Union (24) 271-271
The lower limit of visible traces of penetrative movement in quartz‐rich rocks can be defined by studies of orientations and mutual relations of grains. Intensity of deformation in the central Appalachians decreases gradually from the crystalline Piedmont toward the north, northwest, and west perpendicular to the regional trend. The author...
Structural determinations from diamond drilling
John Beaver Mertie
1943, Economic Geology (38) 298-312
Several problems may arise in the geometrical determinations of strike and dip from core drilling. If the stratigraphic or structural surfaces are plane, as the bedding planes of a homocline, two problems may exist, depending upon whether the drill cores do or do not penetrate to some recognizable horizon. The...

Notes on the early history of water-well drilling in the United States
C.W. Carlston
1943, Economic Geology (38) 119-136
The standard cable-tool drilling rig was invented and developed in drilling salt wells in the West Virginia-Ohio-Pennsylvania region during the twenty years following the successful completion of the first drilled well in 1808 by the Ruffnet brothers at the Great Buffalo Lick near Charleston, West Virginia. Some time previous to...
Supplemental report of the United States members of the International Board of Inquiry for the Great Lakes fisheries
Hubert R. Gallagher, John Van Oosten
1943, Report, International Board of Inquiry for the Great Lakes Fisheries, Report and Supplement
This is a supplement to the report of the International Board of Inquiry relative to the preservation and development of the Great Lakes fisheries as provided by an exchange of notes between Canada and the United States on February 29, 1940. The report aimed to present in a very...
Report of the International Board of Inquiry for the Great Lakes Fisheries
Hubert R. Gallagher, A.G. Huntsman, D. J. Taylor, John Van Oosten
1943, Report, International Board of Inquiry for the Great Lakes Fisheries, Report and Supplement
This is the report of the International Board of Inquiry relative to the preservation and development of the Great Lakes fisheries as provided by an exchange of notes between Canada and the United States on February 29, 1940. The report aims to present in a very brief manner the...
Determination of iron in the presence of chromium and titanium with the Jones reductor
F. S. Grimaldi, R.E. Stevens, M. K. Carron
1943, Industrial and Engineering Chemistry (15) 387-388
Sulfuric acid solutions of titanous and chromous sulfates, obtained by passage through the Jones reductor, are oxidized by aeration for from 5 to 10 minutes in the presence of a trace of copper sulfate as a catalyst. Ferrous sulfate is essentially unoxidized and is titrated with permanganate after aeration. Best...
Determination of small amounts of molybdenum in tungsten and molybdenum ores
F. S. Grimaldi, R. C. Wells
1943, Industrial and Engineering Chemistry (15) 315-316
A rapid method has been developed for the determination of small amounts of molybdenum in tungsten and molybdenum ores. After removing iron and other major constituents the molybdenum thiocyanate color is developed in water-acetone solutions, using ammonium citrate to eliminate the interference of tungsten. Comparison is made by titrating a...
