FINDINGS OF A SYMPOSIUM ON COAL QUALITY.
The U. S. Geological Survey (USGS) has been doing research on coal quality for almost a century. Most of the work of the USGS regarding coal went into efforts to assess the quantity of coal in the United States, not the quality. On April 9-11, 1985, the U. S. Geological Survey, along with cosponsors - the Association of American State Geologists, the U. S. Department of Energy, the Electric Power Research Institute, and the U. S. Environmental Protection Agency - convened a symposium on coal quality at the headquarters of the USGS in Reston, Virginia. The coal-quality symposium provided a forum for the discussion of a wide variety of topics with regard to coal-quality research and related activities. The coal community took advantage of that opportunity to recommend a large agenda of coal-research needs, not only for the USGS but for the entire spectrum of organizations that either actively pursue or fund research on coal quality.
A reconnaissance geochemical survey of the Clarion River Roadless Area, Allegheny National Forest, Elk County, Pennsylvania
Semiquantitative emission spectrographic analyses for 31 elements were determined on 9 stream-sediment samples and 18 bedrock samples from the Clarion River Roadless Area, Elk County, Pennsylvania. All sample localities are given in Universal Transverse Mercator (UTM) coordinates. Brief descriptions of bedrock samples are also included. Rocks analyzed are mostly sandstone, and siltstone. The analytical data do not indicate the presence of mineralized rock in the study area.
A reconnaissance geochemical survey of the Allegheny Front and Hickory Creek Roadless Areas, Allegheny National Forest, Warren County, Pennsylvania
A reconnaissance geochemical survey of the Allegheny Front and Hickory Creek Roadless Areas, Warren County, Pennsylvania, was made by members of the U.S. Geological Survey (USGS) to test for indistinct or unexposed mineral deposits that might be recognized by geochemical halos. Analyses using semiquantitative emission spectrography and atomic absorption for 32 elements were performed on 21 stream-sediment samples and 31 bedrock samples from the Allegheny Front tract, and on 23 stream-sediment samples and 6 bedrock samples from the Hickory Creek tract. Bedrock samples analyzed are primarily sandstone, siltstone and shale. Neither major chemical anomalies nor obviously anomalous chemical-element concentrations related to mineralized bedrock were indicated in the geochemical survey. Metallic mineral deposits were not identified in the study area during the survey, which is consistent with other studies reported in the literature for the surrounding region. The lithologic units exposed in the roadless areas do not commonly host metallic deposits in the surrounding region, and the probability is low that such deposits occur in the roadless areas.
