The Conterminous United States Mineral Appraisal Program; background information to accompany folio of geologic, geochemical, geophysical, and mineral resources maps of the Walker Lake 1 degree x 2 degrees Quadrangle, California and Nevada
John Harris Stewart, M.A. Chaffee, J. C. Dohrenwend, D. A. John, R. W. Kistler, F. J. Kleinhampl, W. D. Menzie, Donald Plouff, L. C. Rowan, Norman J. Silberling
1984, Circular 927
The Walker Lake 1? by 2? quadrangle in eastern California and western Nevada was studied by an interdisciplinary research team to appraise its mineral resources. The appraisal is based on geological, geochemical, and geophysical field and laboratory investigations, the results of which are published as a folio of maps, figures,...
The Alaskan Mineral Resource Assessment Program: Guide to information contained in the folio of geologic and mineral-resource maps of the Medfra quadrangle, Alaska
William Wallace Patton, E. J. Moll, Harley D. King
1984, Circular 928
The Medfra quadrangle in west-central Alaska was investigated by a multidisciplinary team of geoscientists to assess its mineral resources. This Circular is intended to serve as a guide to a folio of 13 separate Open-File Reports covering various aspects of these investigations, including geology, bedrock and stream-sediment geochemistry, potassium-argon dating,...
Discharge ratings at gaging stations
E.J. Kennedy
1984, Techniques of Water-Resources Investigations 03-A10
A discharge rating is the relation of the discharge at a gaging station to stage and sometimes also to other variables. This chapter of 'Techniques of Water-Resources Investigations' describes the procedures commonly used to develop simple ratings where discharge is related only to stage and the most frequently encountered types...
Phosphate rock resources of the United States
James Bachelder Cathcart, Richard Porter Sheldon, Robert A. Gulbrandsen
1984, Circular 888
In 1980, the United States produced about 54 million tons of phosphate rock, or about 40 percent of the world's production, of which a substantial amount was exported, both as phosphate rock and as chemical fertilizer. During the last decade, predictions have been made that easily ruinable, low-cost reserves of...
The Georges Bank monitoring program, 1984: Analysis of trace metals in bottom sediments during the second year of monitoring
Michael H. Bothner, R.R. Rendigs, Esma Campbell, M. W. Doughten, C.M. Parmenter, M. J. Pickering, R. G. Johnson, J.R. Gillison
1984, Circular 936
Of the 12 elements analyzed in bulk (undifferentiated) sediments collected adjacent to drilling rigs on Georges Bank, only barium was found to increase in concentration during the drilling period (July 1981 until September 1982). The maximum postdrilling concentration of barium (a major element in drilling mud) reached 172 ppm in...
The Georges Bank monitoring program 1983: Analysis of trace metals in bottom sediments
Michael H. Bothner, R.R. Rendigs, Esma Campbell, M. W. Doughten, P. J. Aruscavage, A. F. Dorrzapf, R. G. Johnson, C.M. Parmenter, M. J. Pickering, D. C. Brewster, F. W. Brown
1984, Circular 915
From July 1981, when drilling began on Georges Bank, to May 1982, the concentration of barium, a major element in drilling mud, has increased by a factor of 3.5 in bulk sediments 200 m from the drill site in block 410 and by a factor of 2.3 at the drill...
Water resources of the Yap Islands
Otto Van der Brug
1984, Open-File Report 82-357
The Yap Islands consist of four major islands, Yap, Gagil-Tamil, Maap, and Rumung. Of these, Yap Island has more than half the total land area, most of the population, and almost all of the economic development. The islands of Maap and Rumung together compose only 15 percent of the land...
Hydrologic data for aquifers in Philadelphia, Pennsylvania
G. N. Paulachok, C. R. Wood, L.J. Norton
1984, Open-File Report 83-149
Selected data on the ground-water resources of Philadelphia, Pennsylvania, are presented in this report. Information including water levels and data on aquifers is tabulated for 828 wells and 3 sumps. Chemical analyses are given for 1,467 water samples obtained from 205 sites and include 103 analyses for trace elements and...
Reconnaissance geology of the Zarghat Quadrangle, sheet 26/40 B, Kingdom of Saudi Arabia
J. E. Quick
1984, Open-File Report 84-794
The Zarghat quadrangle is located in the northern Precambrian shield of Saudi Arabia between lat 26°30' and 27°00' N. and long 41°00' and 41°30 ' E. The area is underlain by three Precambrian volcanosedimentary units and a range of Precambrian dioritoid and granitoid plutonic intrusive rocks. Paleozoic(?) sandstone crops out...
Compilation of data collected and derived for water years 1980 and 1981 for the purpose of water-quality modeling of the lower Ouachita River and selected tributaries, south-central Arkansas
J. C. Petersen, E. E. Morris
1984, Open-File Report 84-727
This report represents water-quality, sediment oxygen demand, phytoplankton, periphyton, bacteria, instantaneous and mean-daily discharge, stream geometry, time of travel, reaeration data and other water quality collected on the lower Ouachita River (from just upstream of Little Missouri River to Lock and Dam 6), West Two Bayou, Smackover Creek, Haynes Creek...
