Semiquantitative spectrographic analysis and rank correlation in geochemistry
Francis J. Flanagan
1956, Trace Elements Investigations 628
The rank correlation coefficient, rs, which involves less computation than the product moment correlation coefficient, r, can be used to indicate the degree of relationship between two elements. The methods is applicable in situations where the assumptions underlying distribution correlation theory may not be satisfied. Semiquantitative spectrographic analyses can be...
Pyrite-uranium polycrystal
A.G. King
1956, Trace Elements Memorandum 1012
A texture was observed in a sample of ore in 'Which pyrite and uraninite occurred as thin alternate layers paralleling crystal faces of a pyrite nucleus. This texture could be formed either by replacement or by syntaxis. Although syntactic growth forming polyerystals of two chemically dissimilar minerals has not been...
Ephemeral streams - Hydraulic factors and their relation to the drainage net
Luna Bergere Leopold, John P. Miller
1956, Professional Paper 282-A
The hydraulic factors of width, depth, velocity, and suspended sediment load of ephemeral streams near Santa Fe, N. Mex., were measured during flood flow. Later, channel slope was measured. These flood-flow data, in conjunction with an analysis of drainage-basin configuration by the methods proposed by Horton, are used to determine...

C. S. Denny
1956, Professional Paper 288
Potter County is located in the Appalachian Plateaus of north-central Pennsylvania and contains the headwaters of the Genesee River, the Allegheny River, and the Susquehanna River. Drift of Wisconsin age covers the northeastern part of the county. This study includes a detailed survev of the surficial deposits of the Genesee...
Geology and mineral resources of the Ivanpah quadrangle, California and Nevada
D. F. Hewett
1956, Professional Paper 275
The Ivanpah quadrangle covers about 3,900 square miles in the northeastern part of the Mojave Desert of southeastern California and southern Nevada. It includes many mountain ranges 6,000 to 7,000 feet in altitude, and a single peak, Potosi Mountain, attains 8,504 feet. The ranges are separated by broad alluvial filled...
Geology of Saipan, Mariana Islands; Part 1, General geology
Preston E. Cloud Jr., Robert George Schmidt, Harold W. Burke
1956, Professional Paper 280-A
Saipan, situated about 15° N. and 146° E., is one of the larger and more southerly of the Mariana Islands. The 15 small islands of this chain are strung along an eastwardly convex ridge for more than 400 miles north to south, midway between Honshu and New Guinea and about...
