Perlite Resources of the United States

Description: Abstract: This report abstracts the published information on geologic occurrence and distribution of perlite in the United States. Perlite is important in the growing light-weight aggregates industry. The geology and petrology of perlite are described and brief mention is made of mining, milling, processing, economic factors, and reserve figures where known. A table of analyses of the rhyolitic, latitic, and dacitic perlite, welded tuff, pitchstone, and obsidian is included mainly to show the water content. The index map shows known deposits and the geology of areas in which possible deposits may be found. The locations of processing plants are indicated to show their economic relationship to the deposits and to markets.

Strategic Graphite, A Survey

Description: From abstract: Strategic graphite consists of certain grades of lump and flake graphite for which the United States is largely or entirely dependent on sources abroad. Lump graphite of high purity, necessary in the manufacture of carbon brushes, is imported from Ceylon, where it occurs in vein deposits. Flake graphite, obtained from deposits consisting of graphite disseminated in schists and other metamorphic rocks, is an essential ingredient of crucibles used in the nonferrous metal industries and in the manufacture of lubricants and packings. High-quality flake graphite for these uses has been obtained mostly from Madagascar since World War I. Some flake graphite of strategic grade has been produced, however, from deposits in Texas, Alabama, and Pennsylvania. The development of the carbon-bonded crucible, which does not require coarse flake, should lessen the competitive advantage of the Madagascar producers of crucible flake.

Simplified Geologic Map Showing Uranium Deposits and Principal Ore-Bearing Formations of the North Central Cordilleran Foreland Region

Description: From introduction: The Cordilleran Foreland has been defined by Osterwald (1956, p. 1) as "a region containing distinctive structural elements that forms a broad north-south belt parallel to and east of the Cordilleran geanticline...." The location of these tectonic regions is shown in figure 4 of this report. region are an important potential source of uranium in the United States. The accompanying maps (figs. 1, 2, and 3) show the location of most of the known uranium deposits and the localities from which samples, containing 0.01 or more percent uranium, or uranium minerals, have been obtained. The outcrop patterns of the principal ore-bearing formations are from the sources indexed on each map.
