Resource potential for commodities in addition to Uranium in sandstone-hosted deposits Resource potential for commodities in addition to Uranium in sandstone-hosted deposits
Sandstone-hosted deposits mined primarily for their uranium content also have been a source of vanadium and modest amounts of copper. Processing of these ores has also recovered small amounts of molybdenum, rhenium, rare earth elements, scandium, and selenium. These deposits share a generally common origin, but variations in the source of metals, composition of ore-forming solutions, and...

Linking the Central and Southern Appalachian Blue Ridge: What We Know and Don’t Know about Stratigraphy, Structure, Tectonism, and Regional Correlation in the Eastern Blue Ridge of Virginia Linking the Central and Southern Appalachian Blue Ridge: What We Know and Don’t Know about Stratigraphy, Structure, Tectonism, and Regional Correlation in the Eastern Blue Ridge of Virginia
The transition from Neoproterozoic Lynchburg Group rocks on the eastern limb of the para-autochthonous Blue Ridge anticlinorium in central Virginia to the fault-bounded Ashe Formation and Alligator Back Formation in southern Virginia has been a source of intense debate and speculation for decades. There are fundamental differences in the tectonogenetic interpretation for these rock...

Hydrogeology of Virginia Hydrogeology of Virginia
The hydrogeology of Virginia documented herein is in two parts. Part 1 consists of an overview and description of the hydrogeology within each regional aquifer system in the Commonwealth. Part 2 includes discussions of hydrogeologic research topics of current relevance including: 1. the Chesapeake Bay impact structure, 2. subsidence/compaction in the Coastal Plain, 3. groundwater age and...

Ferromanganese crusts and nodules, rocks that grow Ferromanganese crusts and nodules, rocks that grow
Ferromanganese (Fe-Mn) crusts and nodules are marine sed- imentary mineral deposits, composed mostly of iron and manganese oxides. They precipitate very slowly from seawa- ter, or for nodules also from deep-sea sediment pore waters, recording the chemical signature of these source waters as they grow. Additional elements incorporate via sorption pro- cesses onto the Fe-Mn oxides...

Shifting patterns in SAV species diversity and community structure Shifting patterns in SAV species diversity and community structure
This chapter examines the shifting patterns in Chesapeake SAV community structure and the potential environmental variables that explain variation in species composition patterns at both long and short time periods. Bay-wide species occurrence data sets are summarized. These data show that twenty-seven or more species of SAV are found within the tidal Chesapeake Bay. Seventeen of these...
