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
