Mineral resource potential map of the Lusk Creek Roadless Area, Pope County, Illinois

No abstract available.

Mineral resource potential map of the Lye Brook Wilderness, Bennington and Windham counties, Vermont

The Lye Brook Wilderness contains no significant mineral deposits. Although the Cheshire Quartzite is a potential source of low-grade silica sand and crops out in a large area within the wilderness, its degree of induration and relative inaccessibility make its use prohibitive. No major concentation of base metals exist within the Precambrian rocks, although they contain the highest metal concentr

Mineral resource potential map of the Mount Eddy and Castle Crags Roadless Areas, Shasta, Siskiyou, and Trinity counties, California

Although ultramafic terranes such as that underlying the Mount Eddy and Castle Crags Roadless Areas may contain chromite, nickel, platinum-group metals, cobalt, and asbestos, there are no significant identified concentrations of these resources within the roadless areas. Platinum-group metals were sought but not detected in stream-sediment concentrates, although this does not rule out their possib

Mineral resource potential map of the Natural Area Roadless Area, Baker County, Florida

The Natural Area Roadless Area, which is in the Osceola National Forest in Baker County, Fla., is underlain by sedimentary rocks containing phosphate deposits that are not a potential mineral resource by todays standards. The region has a low potential for oil and gas and virtually no potential for other valuable minerals. The phosphate deposits are either slightly low in tonnage and P2O5 content,
