Geological Survey research 1964
Water Resources Division, U.S. Geological Survey
1964, Professional Paper 501-D
This collection of 43 short papers is the last of the chapters of Geological Survey Research 1964. The papers report on scientific and economic results of current work by members of the Geologic, Conservation, Water Resources, and Topographic Divisions of the U.S. Geological Survey. Some of the papers present results...

Surface water records of Indiana, 1964
Water Resources Division, U.S. Geological Survey
1964, Report
The surface-water records for the 1964 water year for gaging stations, partial-record stations, and miscellaneous sites within the State of Indiana are given in this report. For convenience there are also included records for a few pertinent gaging stations in bordering States. The records were collected and computed by the...
Hidden Recharge
J. H. Feth
1964, Ground Water (2) 14-17
“Hidden recharge” is defined as subsurface percolation of water from basin‐margin mountains directly into aquifers of the valley basins. It is an important, and sometimes neglected, item in hydrologic equations. Locally, geologic conditions permit inter‐basin circulation of ground water. The concept that ground‐water basins necessarily terminate at the contact between...
Geohydrologic analogies between the Jordan Valleys of Utah and the holy land
Edward Bradley
1964, International Association of Scientific Hydrology - Bulletin (9) 12-23
The biblical Jordan River Valley, which extends from Lake Tiberias (the Sea of Galilee) to the Dead Sea, is decidedly similar to the Jordan River Valley of Utah, which joins Lake Utah and Great Salt Lake. Both Jordan Rivers drain relatively large fresh-water lakes and also are major sources of discharge into large salty lakes that have no outlets to the ocean.The...
Deep geothermal brine near Salton Sea, California
Donald E. White
1964, Bulletin Volcanologique (27) 369-370
A well drilled for geothermal power near Salton Sea in Imperial Valley, Calif., is 5,232 feet deep; it is the deepest well in the world (1962) in a high-temperature hot spring area. In the lower half of the hole temperatures are too high to measure with available equipment, but are...
Oriented lakes and lineaments of northeastern Bolivia
George Plafker
1964, GSA Bulletin (75) 503-522
Strongly oriented lineaments, defined by lake shores and stream and vegetation alignments, are distributed throughout more than 45,000 square miles of the Beni basin in northeastern Bolivia. The area in which these features occur is a flat, poorly drained, lake-studded plain. It is underlain by flat-lying, poorly consolidated, continental clastic...
Thorne Cave, northeastern Utah: Geology
Harold E. Malde, Asher P. Schick
1964, American Antiquity (30) 60-73
Geologic interest in Thorne Cave stems from its link with valley alluvium along Cliff Creek, which accumulated to a height of 48 ft., continued to build up another 13 ft. while men lived here, and then reached 30 ft. higher-sealing in the signs of man. Mineralogic study shows that ground water then circulated...
Mineral paragenesis and zoning in the central Kentucky mineral district
J. L. Jolly, A. V. Heyl
1964, Economic Geology (59) 596-624
The Central Kentucky mineral district occupies the greater part of the Blue Grass lowland of Kentucky, which lies astride the Lexington dome and the Cincinnati arch. The oldest exposed rocks of the mineralized area are limestones of Middle Ordovician age. The paragenesis throughout the district is constant and traceable, although the relative abundance of minerals varies from vein to vein....
