Metamorphic differentiates in the blackbird mining district, Lemhi County, Idaho
Wayne A. Roberts
1953, Economic Geology (48) 447-456
Quartz pods and quartz veins devoid of economic minerals occur in the cobalt-copper mineralized Blackbird mining district in Lemhi County, Idaho. These barren quartz bodies are found in regionally and thermally metamorphosed rocks of the Yellowjacket formation (Belt series) of Pre-cambrian age and are believed to be derived from the enclosing quartz-biotite and quartz-biotite-garnet-chloritoid schists by metamorphic differentiation. Other rocks that possibly are...
Petrology of granophyre in diabase near Dillsburg, Pennsylvania
Preston E. Hotz
1953, Geological Society of America Bulletin (64) 675-704
Small bodies of granophyre occur in the upper part of diabase bodies of Triassic age in southeastern Pennsylvania. One near Harrisburg was penetrated by a diamond-drill. Drill core specimens show a gradation from diabase to granophyre.New data include 10 chemical analyses, spectrographic determinations of trace elements, and the results of...
The influence of ground‐water storage on the runoff in the San Bernardino and eastern San Gabriel Mountains of Southern California
Harold C. Troxell
1953, Eos, Transactions, American Geophysical Union (34) 552-562
The steep and rugged mountains of Southern California contain considerable ground‐water storage. A large portion of the runoff is seepage from this storage The variations in runoff distribution depend on the geology, physiography, and soil cover of these mountain areas....
Stratigraphic sections of the phosphoria formation in Utah, 1949-1951
T. M. Cheney, R.A. Smart, R.G. Waring, M.A. Warner
1953, Trace Elements Investigations 360
As part of a comprehensive investigation of the phosphate deposits of the western field begun in 1947, the U.S. Geological Survey has measured and sampled the full thickness of the Permian Phosphoria formation and its partial correlative, the Park City formation, at many localities in Utah and other states....

A field method for the determination of titanium in rocks
Leonard Shapiro, Walter Wallace Brannock
1953, Economic Geology (48) 282-287
About 4 mg of rock powder measured with a scoop is fused with potassium bisulfate in a test tube. Tiron is added to the cool melt and the mixture is dissolved in a buffer solution. Sodium dithionite is added and the approximate concentration of TiO 2 is determined by comparing the resulting...
Terminology for stratification and cross-stratification in sedimentary rocks
Edwin D. McKee, Gordon W. Weir
1953, GSA Bulletin (64) 381-390
A terminology is suggested to aid the field geologist in describing the structures of stratified and cross-stratified rock units. Qualitative terms describing the character of rock layering are stratification, stratum, cross-stratification, cross-stratum, set, coset, and composite set. Quantitative terms applying to the thickness of stratification are very thick-bedded, thick-bedded, thin-bedded, very thin-bedded, laminated, and thinly laminated. Quantitative terms...
Carnotite resources of the Dolores bench, Montrose County, Colorado
Daniel Alfred Jobin
1953, Trace Elements Investigations 214
The Dolores bench is about 2 miles northwest of Uravan, Montrose County, Colo. From 1913 to November 1952 about 95,000 short tons of ore averaging 0.40 percent U3O8 and 2.0 percent V2O5 was mined from the Dolores bench. The production represents three periods of activity--1913-18, 1938-43, and 1948-52. The ore deposits...
Stratigraphic sections of the Phosphoria formation in Wyoming, 1952
R.P. Sheldon, E. R. Cressman, L.D. Carswell, R.A. Smart
1953, Trace Elements Investigations 378
The U.S. Geological Survey has measured and sampled the Phosphoria formation of Permian age at many localities in Wyoming and adjacent states. These data will not be fully synthesized for many years, but segments of the data, accompanied by little or no interpretation, are published as preliminary reports as...
Stratigraphic sections of the Phosphoria formation in Wyoming, 1951
Thomas McGriffin Cheney, Richard Porter Sheldon, R.G. Waring, M.A. Warner
1953, Trace Elements Investigations 377
The U.S. Geological Survey has recently measured and sampled the Phosphoria formation at many localities in Wyoming and adjacent states. These data will not be fully synthesized for many years, but segments of the data, accompanied by little or no interpretation, are published as preliminary reports as they are...
