Mines, prospects, and occurrences of metallic (excluding gold), pegmatite, and rare-earth mineral commodities in the Greenville 1° x 2° quadrangle, South Carolina, Georgia, and North Carolina Mines, prospects, and occurrences of metallic (excluding gold), pegmatite, and rare-earth mineral commodities in the Greenville 1° x 2° quadrangle, South Carolina, Georgia, and North Carolina
All of the known mines, prospects, and occurrences of metallic (excluding gold, pegmatite, and rare-earth mineral commodities for the Greenville 1° x 2° quadrangle are tabulated in this report. The table lists, in consecutive order for each county (fig. 1), the map number of each item, which correlates and locates the item on the accompanying Greenville 1° x 2° quadrangle map. The known...

Reconnaissance geologic map of the Sliderock Mountain area, Sweet Grass and Stillwater counties, Montana Reconnaissance geologic map of the Sliderock Mountain area, Sweet Grass and Stillwater counties, Montana
The remains of a deeply eroded Late Cretaceous stratovolcano centered near Sliderock Mountain dominate the map area. The volcano consists mostly of lahars, although basaltic andesite lava flows are also present. An extensively eroded, weakly mineralized hypabyssal intrusive complex, inferred to represent the volcano's solidified magma chamber, intrudes previously erupted lava flows and...
Shoreline and coastal wetland variability along the west shore of Green Bay, Marinette and Oconto counties, Wisconsin Shoreline and coastal wetland variability along the west shore of Green Bay, Marinette and Oconto counties, Wisconsin
Coastal wetland ecosystems along the Great Lakes shorelines are extremely valuable natural resources. They provide numerous environmental and recreational benefits, and they serve as critical habitats for fish and wildlife populations. In general terms, wetlands can be defined as lands transitional between terrestrial and aquatic systems; they are characterized by periodic submergence or...
Temporal variability of shoreline positions and coastal wetlands along lower Green Bay, Oconto and Brown counties, Wisconsin Temporal variability of shoreline positions and coastal wetlands along lower Green Bay, Oconto and Brown counties, Wisconsin
The positions of shorelines and the areal extent of adjacent coastal wetland tracts in the Great Lakes region have exhibited substantial temporal variability during both prehistoric and historical times. Shoreline migration has resulted in environmental problems such as flooding and the coastal erosion of lakefront property, as well as the destruction of coastal wetland resources. In the...
