Origin of marcasite and its implications regarding the genesis of roll-front uranium deposits
Martin B. Goldhaber, Richard L. Reynolds
1979, Open-File Report 79-1696
Study of five roll-type uranium deposits (three in Texas and two in Wyoming) has resulted in the recognition of ore-stage marcasite in each deposit. Ore-stage marcasite is identified by its close association with uranium- and vanadium-bearing phases in the ore zones; by its close association with ferroselite at and near...
Analysis of ground water by different laboratories: a comparison of chloride and nitrate data, Nassau and Suffolk counties, New York
Brian G. Katz, Richard K. Krulikas
1979, Open-File Report 79-1063
Water samples from wells in Nassau and Suffolk Counties were analyzed for chloride and nitrate. Two samples were collected at each well; one was analyzed by the U.S. Geological Survey, the other by a laboratory in the county from which the sample was taken. Results were compared statistically by paired-sample...

Analysis of picric acid in water by high-performance liquid chromatography
D.F. Goerlitz
1979, Open-File Report 79-207
Methods for the determination of picric acid (2,4,6, trinitrophenol) in water employing high-performance liquid chromatography are presented. Ion-pair chromatography under an isocratic condition is performed on a reverse-phase column. Picric acid can be determined directly in water at a lower detection limit of 10 micrograms per liter. By use of...

1979, Professional Paper 1086
A subcircular area of about 650 km 2 in northern California and southwestern Oregon is occupied by rocks of the greenschist metamorphic facies called the Condrey Mountain Schist. This greenschist terrane is bordered on the east and west by rocks belonging to the amphibolite metamorphic facies that structurally overlie and...
Enhancement of Landsat images for lineament analysis in the area of the Salina Basin, New York and Pennsylvania
M. Dennis Krohn
1979, Open-File Report 79-533
Digital image processing of Landsat images of New York and Pennsylvania was undertaken to provide optimum images for lineament analysis in the area of the Salina Basin. Preliminary examination of Landsat images from photographic prints indicated sufficient differences between the spectral bands of the Landsat Multispectral Scanner (MSS) to warrant...

Clastic dikes of Heart Mountain fault breccia, northwestern Wyoming, and their significance
W. G. Pierce
1979, Professional Paper 1133
Structural features in northwestern Wyoming indicate that the Heart Mountain fault movement was an extremely rapid, cataclysmic event that created a large volume of carbonate fault breccia derived entirely from the lower part of the upper plate. After fault movement had ceased, much of the carbonate fault breccia, here called...
