    Black shale, also called Carboniferous Shale, variety of shale that contains abundant organic matter, pyrite, and sometimes carbonate nodules or layers and, in some locations, concentrations of copper, nickel, uranium, and vanadium. Fossils are rare in the shale and either are replaced by pyrite or are preserved as a film of graphite.

    May 01, 2019 Abstract. Black shales are sedimentary rocks containing 0.5 of organic carbon. They host polymetallic deposits which have been mined for Cu, Ni, Zn, Mn, P, Mo, V, U, Au and PGE platinum group elements. Even sub-economic occurrences provide potential risk of acid rock drainage when exposed to oxic surface environment.
