Exploration for porphyry copper deposits in Pakistan using digital processing of Landsat-1 data
Robert G. Schmidt
1976, Journal of Research of the U.S. Geological Survey (4) 27-34
Rock-type classification by digital-computer processing of Landsat-1 (formerly ERTS-1) multispectral scanner data has been used to select 23 prospecting targets in the Chagai District, Pakistan, 5 of which have proved to be large areas of hydrothermally altered porphyry containing pyrite. The known porphyry copper deposit at Saindak was used as...

Chart of conversion factors: From English to metric system and metric to English system
Water Resources Division, U.S. Geological Survey
1976, Report
The conversion factors in the following tables are for conversion of our customary (English) units of measurement to SI*units, and for convenience, reciprocals are shown for converting SI units back to the English system. The first table contains rule-of-thumb figures, useful for "getting the feel" of SI units or mental...
Man against volcano: The eruption on Heimaey, Vestmann Islands, Iceland
R.S. Williams Jr., J.G. Moore
1976, Report
The U.S. Geological Survey carries out scientific studies in the geological, hydrological, and cartographic sciences generally within the 50 states, but also in cooperation with scientific organizations in many foreign countries for the investigation of unusual earth science phenomena throughout the world. The following material discusses the impact of the...
Nature . . . an environmental yardstick
William T. Pecora
1976, Information and Technology Report 72-21
To one who has spent his professional career in geologic science, conservation always has had special meaning. In the measurements so necessary to his work the geologist develops an integrity in the use of numbers and in the qualifications attending the validity of numbers. Scientific analysis of geologic events and...
