The Mancos Shale is a geologic formation dominated by marine mudrocks below storm wavebase (Kellogg 1977), deposited in the Western Interior Seaway during the Late Cretaceous geologic period. Within this formation are intervals that consist of very-fine to medium-grained sandstones displaying both sheet-like and channel-form geometries, with sedimentary structures that appear wave influenced. The area […]

C53: Characterization of Mine Waste from Tonopah, Nevada: Potential Gold and Silver Recovery and Related Environmental Impacts
Tonopah is a small town in Nevada known for its mining activity and silver production in the early to mid-1900’s. Today, all the mines are closed, yet their impact on the town still remains evident in the form of large mine waste piles. This study is being carried out in an effort to characterize Tonopah’s […]
