Increased fluorine consumption (U.S. Bureau of Mines, 1946-1971) coupled with limited proved reserves has stimulated extensive exploration for fluorine and intensive research into developing new sources of fluorine or substitutes. A summary of the distribution, geochemical and geologic environments, and production history of selected fluorspar occurrences, deposits, and districts is provided here 

In the Fairbanks area, the effects of development on the geologic environment must be considered in determining proper land use. Persons concerned with the land, especially land planners, developers, public officials, engineers, architects, financial advisors, and educators, must be aware of recognizable geologic features that may prove hazardous; only then can proper and economical land usage be

The primary controlling factors determining ground-water conditions in the Fairbanks D-1 SW quadrangle are (1) topographic position, (2) water-bearing characteristics of the rocks, and (3) distribution of permafrost. These interrelated factors generally limit the conditions in any particular area. Basic data from the geologic map of the Fairbanks D-1 SW quadrangle (Map I-949, Pewe and others, in p

The primary factors that determine ground-water conditions in the Fairbanks D-2 NE quadrangle are (1) topographic position, (2) water-bearing characteristics of the rocks, and (3) distribution of permafrost. These interrelated factors generally limit the conditions in any particular area.

The primary factors that determine ground-water conditions in the Fairbanks D-2 NW quadrangle are (1) topographic position, (2) water-bearing characteristics of the rocks, and (3) distribution of permafrost. These interrelated factors generally limit the conditions in any particular area.

The primary controlling factors determining ground-water conditions in the Fairbanks D-2 SE quadrangle are (1) topographic position, (2) water-bearing characteristics of the rocks, and (3) distribution of permafrost.
