Distribution and abundance of lead in stream sediments and moraine debris, McCarthy Quadrangle, Alaska
Keith Robinson, C. M. McDougal, G.W. Day, Theodore Billings
1976, Miscellaneous Field Studies Map 773-G
A geochemical survey was conducted in the McCarthy quadrangle, Alaska, to identify areas containing anomalous concentrations of various metallic and nonmetallic elements. This study incorporates the results of analyses for lead, from 1,453 stream sediment and glacial moraine debris samples collected in the quadrangle, and analyzed by the U.S. Geological...
Composite geochemical map of anomalous copper and molybdenum distribution in the Tanacross Quadrangle, Alaska
G.C. Curtin, G.W. Day, R. M. O’Leary, S.P. Marsh, R. B. Tripp
1976, Miscellaneous Field Studies Map 767-M
This geochemical map delineates drainage basins in which either anomalous copper, molybdenum, or both copper and molybdenum were detected in at least one of four sample media: (A) the oxide residue (the oxalic-acid-leachable fraction) of the stream sediment, (B) the minus-80-mesh stream sediment, (C) the ash of streambank sod (mixed...
Distribution and abundance of arsenic and mercury in stream sediments and moraine debris, McCarthy quadrangle, Alaska
Keith Robinson, R. M. O’Leary, C. M. McDougal, Theodore Billings
1976, Miscellaneous Field Studies Map 773-I
A geochemical survey was conducted in the McCarthy quadrangle Alaska, to identify areas containing anomalous concentrations of various metallic and nonmetallic elements. This study incorporates the results of analyses for arsenic and mercury from 426 and 424 stream sediment and glacial moraine debris samples collected in the quadrangle, and analyzed...
Composite geochemical map of anomalous lead and zinc distribution in the Tanacross Quadrangle, Alaska
G.C. Curtin, G.W. Day, R. M. O’Leary, R. B. Tripp, R.B. Carten
1976, Miscellaneous Field Studies Map 767-N
This geochemical map shows drainage basins in which either anomalous lead, zinc, or both lead and zinc values were detected in at least one of four sample media: (A) the oxide residue (the oxalic-acid-leachable fraction) of the stream sediment, (B) the minus-80-mesh stream sediment, (C) the ash of streambank sod (mixed...
Geochemical maps showing the distribution and abundance of arsenic and mercury in the Tanacross Quadrangle, Alaska
G.C. Curtin, R. M. O’Leary, R.B. Carten
1976, Miscellaneous Field Studies Map 767-J
This series of geochemical maps shows the distribution of arsenic and mercury in the minus-80-mesh stream sediment and of arsenic in the ash of streambank sod (mixed organic and inorganic material) collected beneath the water level. The geochemical data are plotted on a base map that shows generalized geology and...
Geochemical maps showing the distribution and abundance of tin in the Tanacross Quadrangle, Alaska
G.C. Curtin, G.W. Day, S.P. Marsh, R. M. O’Leary, R. B. Tripp
1976, Miscellaneous Field Studies Map 767-K
This series of geochemical maps shows the distribution of tin in three sample media: (A) the oxide residue (the oxalic-acid-leachable fraction) of the stream sediment, (B) the minus-80-mesh stream sediment, and (C) the ash of aquatic bryophytes (mosses). The geochemical data are plotted on a base map that shows generalized geology...
Geochemical maps showing the distribution and abundance of zinc in the Tanacross Quadrangle, Alaska
G.C. Curtin, G.W. Day, R. M. O’Leary, S.P. Marsh, R. B. Tripp
1976, Miscellaneous Field Studies Map 767-I
This series of geochemical maps shows the distribution of zinc in four sample media: (A) the oxide residue (oxalic-acid-leachable fraction) of the stream sediment, (B) the minus-80-mesh steam sediment, (C) the ash of streambank sod (mixed organic and inorganic material) collected beneath the water level, and (D) the ash of...
Maps showing mineralogical and geochemical data for heavy-mineral concentrates in the Tanacross quadrangle, Alaska
R. B. Tripp, G.C. Curtin, G.W. Day, R. C. Karlson, S.P. Marsh
1976, Miscellaneous Field Studies Map 767-O
This series of maps showing the following data for heavy mineral concentrates: distribution and abundance of selected ore-related minerals, distribution and abundance of copper in the magnetic fraction, and distribution and abundance of lead, copper, tin, beryllium, tungsten and bismuth in the nonmagnetic fraction. The data are plotted on base...
Map of coal-mining features, Allegheny County, Pennsylvania
W.E. Davies, J. S. Pomeroy, W. R. Kohl
1976, Miscellaneous Field Studies Map 685-C
This map is one result of a series of studies sponsored by the Appalachian Regional Commission as part of a larger U.S. Geological Survey program of environmental analysis of a part of southwestern Pennsylvania. The map summarizes surface features resulting from coal mining. The distribution of surface features is largely...
Geochemical maps showing the distribution and abundance of lead in the Tanacross Quadrangle, Alaska
G.C. Curtin, G.W. Day, R. M. O’Leary, S.P. Marsh, R. B. Tripp
1976, Miscellaneous Field Studies Map 767-H
This series of geochemical maps shows the distribution of lead in four sample media: (A) the oxide residue (the oxalic-acid-leachable fraction) of the stream sediment, (B) the minus-80-mesh stream sediment, (C) the ash of streambank sod (mixed organic and inorganic material) collected beneath the water level, and (D) the ash...
Water resources data for Missouri, water year 1975
Water Resources Division, U.S. Geological Survey
1976, Water Data Report MO-75-1
Water resources data for the 1975 water year for Missouri consist of records of stage, discharge, and water quality of streams; stage, contents, and water quality of lakes and reservoirs. This report contains discharge records for 138 gaging stations; stage and contents for 6 lakes and reservoirs, and water quality...
