A geochemical study of the Rio Pantanos area, Department of Antioquia, Colombia preliminary report
Henry V. Alminas, Elwin L. Mosier
1972, Open-File Report 72-4
Geochemical sampling in the Western Cordillera has delineated an 18 km 2 area anomalous in copper, molybdenum, and silver. Highly anomalous metal contents are found in stream sediment, soil, and outcrop samples collected within this area. The area is underlain by intrusive granodiorite to quartz diorite that has porphyritic and...

John Patrick Albers, Adnan Kalifatcioglu
1972, Open-File Report 72-3
A brief examination of the Bartin-were whether earthquake area was made on September 23 and September 24,1968, by the authors to determine whether or not geologic effects had been produced that were significant enough to warrant further detailed study by the Mineral Research and Exploration Institute of Turkey or by...
Placer deposits of Alaska
Edward Huntington Cobb
1972, Open-File Report 72-71
Placer deposits, in addition to their intrinsic value, serve as indicators of areas of potential development of lode deposits. Any possibility that Alaska may again become an important source of metallic mineral commodities depends in part on an inventory of placer deposits and a knowledge of the geology of their...

1972, Open-File Report 72-259
A keyword-in-context (KWIC) or out-of-context (KWOC) index is a convenient means of organizing information. This keyword index program can be used to create either KWIC or KWOC indexes of bibliographic references or other types of information punched on. cards, typed on optical scanner sheets, or retrieved from various Department of...
Reconnaissance geologic map of the west half of the Solomon quadrangle, Alaska
C.L. Sainsbury, Travis Hudson, Rodney Ewing, William R. Marsh
1972, Open-File Report 72-324
The Solomon quadrangle adjoins the Bering Sea east of Nome, Alaska. It has a common west border with the Nome quadrangle (Sainsbury and others, 1972b) and a common north border with the Bendeleben 1:250,000- scale quadrangle.Part of the area was mapped by Smith (1910), who discussed the rocks in some...

Tectonic map of Liberia based on geophysical and geological surveys
John Charles Behrendt, Cletus S. Wotorson
1972, Open-File Report 72-32
Interpretation of the results of aeromagnetic, total-gamma radioactivity, and gravity surveys combined with geologic data for Western Liberia from White and Leo (1969) and other geologic information allows the construction of a tectonic map of Liberia. The map approximately delineates the boundaries between the Liberian (ca. 2700 m.y.) province in...
