Summary of references to mineral occurrences (other than mineral fuels and construction materials) in the Craig Quadrangle, Alaska

These summaries of references are designed to aid in library research on metallic and nonmetallic (other than mineral fuels and construction materials) mineral occurrences in the Craig quadrangle, Alaska. All references to reports of the Geological Survey, to most reports of the U.S. Bureau of Mines, and to most reports of the State of Alaska Division of Geological and Geophysical Surveys and its predecessor State and Territorial agencies released before May 1, 1978, are summarized. Certain, mainly statistical, reports such as the annual Minerals Yearbook of the U.S. Bureau of Mines and the biennial and annual reports of the State of Alaska Division of Geological and Geophysical Surveys and its predecessor State and Territorial agencies are not included. This report is divided into three parts: a section made up of summaries of references arranged alphabetically by occurrence name; a section that lists synonyms for names in the first section, claim names, and the names of operators and owners of mines and prospects; and a section that lists, by author, all references summarized in the first section.

Selected field data collected in 1975, northeastern Craig Quadrangle, southeastern Alaska

This report consists of a computer printout of geologic field data recorded by H.C. Berg from July 2 to July 20, 1975 in the part of the Craig (CR) 1:250,000-scale quadrangle northeast of Clarence Strait (figs. 1 and 2). It contains edited and revised observations on structure, lithology, mineralogy, metamorphism, and mineral occurrences. Areas covered by the observations include southern Etolin and adjacent islands and part of Cleveland Peninsula, including 5 sites in the Ketchikan (KC) quadrangle immediately adjacent to the Craig quadrangle (fig. 2). A preliminary geologic map incorporating the data has been released (Berg and others, 1976). The printout includes the latitude-longitude coordinates of each field station, so that the user can locate the observations within a few metres on larger-scale topographic maps than figure 2. The purpose of this report is to provide an organized file of detailed field observations to supplement and amplify a companion geologic map. The combined reports thus constitute a complete record of available information to serve as wide a range of potential users as possible. The information in this report was transferred from geologic fieldsheets (fig. 3) to computer storage using the method described by Hudson and others (1975). A. Marianne Fujii transcribed the data from the fieldsheets; Betsy Yount and Frances Wahl helped to update the computer file and prepare it for publication; and Bruce Salem wrote the interactive computer program that greatly facilitated entry of the fieldnotes into the computer file.
