James Carlton Taylor
1976, Circular 730
Offshore southern California is part of a much larger Pacific continental margin, and the two areas have a similar geologic history at least as far back as middle Tertiary time. Assessment of the petroleum potential of the offshore Southern California borderland is accomplished by examining the adjacent highly explored productive...
Guidelines for sample collecting and analytical methods used in the U.S. Geological Survey for determining chemical composition of coal
Vernon Emanuel Swanson, Claude Huffman
1976, Circular 735
This report is intended to meet the many requests for information on current U.S. Geological Survey procedures in handling coal samples. In general, the exact type and number of samples of coal and associated rock to be collected are left to the best judgment of the geologist. Samples should be of...
Guidelines for collection and field analysis of ground-water samples for selected unstable constituents
