Posssible extension of mineral belts, northern part of Coeur d'Alene district, Idaho
Garland Bayard Gott, Joseph Moses Botbol
1974, Open-File Report 74-67
The ore deposits in the northern part of the Coeur d'Alene district are located within rocks of the Belt Supergroup that have been intruded by Cretaceous quartz monzonites. Lead-zinc-silver replacement veins constitute most of the deposits. The geometry of the district has been modified by post-ore faulting along the Osburn,...
Saline ground-water resources of Lee County, Florida
Durward Hoye Boggess
1974, Open-File Report 74-247
Lee County, an area of 786 square miles (1260 square kilometres) on the southwest coast of Florida, is underlain at depths greater than 400 feet (120 metres) by formations containing saline water. Two saline water-bearing zones occur within the depth interval 400 to 1,200 feet (120 to 370 metres); the...
Water in the Great Basin region; Idaho, Nevada, Utah, and Wyoming
Don Price, Thomas E. Eakin
1974, Hydrologic Atlas 487
The Great Basin Region is defined to include the drainage of the Great Basin physiographic section (Fennman, 1931) in Idaho, Nevada, Utah, and Wyoming. In October 1966, the President’s Water Resources Council requested that a comprehensive framework study be made in the Great Basin Region under the leadership of the...
Geologic and hydrologic control of chloride contamination in aquifers at Brunswick, Glynn County, Georgia
Dean O. Gregg, Everett Alfred Zimmerman
1974, Water Supply Paper 2029-D
Water from a brackish-water zone (1,050-1,350 ft) has concentrations as high as 2,150 milligrams per liter chloride, and concentrations are suspected to be higher than 3,000 milligrams per liter chloride. This brackish water has been identified as the source of the water that contaminates the upper and lower fresh-water-bearing zones...
Bedrock geologic map of the Greenwood quadrangle, Marquette County, Michigan
William F. Cannon
1974, Geologic Quadrangle 1168
The Marquette Iron Range is presently ( 1973) the second largest iron mining district in the United States. Commercial iron deposits, now mostly concentrating-grade ore, are in the Negaunee Iron-formation, which is part of a thick sequence of metasedimentary rocks of Precambrian X age. These rocks are preserved in the...
