Gazetteer of coal-mine lakes in southwestern Indiana
Linda L. Bobo
1979, Open-File Report 79-1639
This gazetteer is a catalog of lakes formed by surface coal mining in southwestern Indiana that are 0.5 acre or larger and in nonactive mine areas. Approximately 1,000 of the lakes are listed by 7.5-minute quadrangle topographic-map name, lake-identification number, latitude and longitude, and county. Other data given are shape...
Geochemical and generalized geologic map showing distribution and abundance of antimony and niobium in stream sediments, Chandalar 1° by 3° quadrangle, Alaska
S.P. Marsh, D.E. Detra, S.C. Smith
1979, Miscellaneous Field Studies Map 878-H
This geochemical map shows the distribution and abundance of antimony (Sb) and niobium (Nb) in -80 mesh (177 micrometers) stream sediment samples in the Chandalar quadrangle, Alaska. The map is one of a series of geochemical maps that together with the background information circular (Reiser and others, 1978) comprise the folio...
Direct analysis of RDX and TNT in water by high-performance liquid chromatography
D.F. Goerlitz
1979, Open-File Report 79-916
A method for the determination of RDX (1,3,5-trinitro-1,3,5-triazacyclohexane) and TNT (2,4,6-trinitrotoluene) directly in water is given. The high-performance liquid chromatographic technique permits detection down to 0.1 microgram per liter in filtered water. No ancillary extraction or concentrating procedures are used....

St. George basin is a long (300 km), narrow (30-50 km) graben whose long axis strikes northwestward, parallel to the continental margin of the southern Bering Sea. Located near the Pribilof Islands, and beneath the virtually featureless Bering Sea shelf, the basin is filled with more than 10 km of...
Paleontologic and stratigraphic relations of phosphate beds in Upper Cretaceous rocks of the Cordillera Oriental, Colombia
Edwin K. Maughan, Francisco Zambrano O., Pedro Mojica G., Jacob Abozaglo M., Fernando Pachon P., Raul Duran R.
1979, Open-File Report 79-1525
Phosphorite crops out in the Cordillera Oriental of the Colombian Andes in rocks of Late Cretaceous age as strata composed mostly of pelletal carbonate fluorapatite. One stratum of Santonian age near the base of the Galembo Member of the La Luna Formation crops out at many places in the Departments...
Saltwater-barrier line in Florida: Concepts, considerations, and site examples
Jerry L. Hughes
1979, Water-Resources Investigations Report 79-75
Construction of canals and enlargement of streams in Florida has been mostly to alleviate impact of floods and to drain wetlands for development. Land drainage and heavy pumpage from coastal water-table aquifers has degraded potable ground and surface water with saltwater. Control of saltwater intrusion is possible through implementation of...

C.C. Kidwell
1979, Open-File Report 79-335
The U.S. Soil Conservation Service is actively engaged in the installation of flood- and soil-erosion reducing structures in Texas under the authority of "The Flood Control Act of 1936 and 1944" and "Watershed Protection and Flood Prevention Act" (Public Law 566), as amended. The Soil Conservation Service has found that...
