The Kupferschiefer of northern central Europe is not only one of the largest sediment-hosted accumulations of copper ores worldwide (largest 1% of deposits with >60 Mt contained Cu) but has also one of the longest continuously documented mining histories, starting from at least 1,199 A.D. in the Mansfeld district of Germany.

Kupferschiefer mineral deposits, Germany Britannica

In mineral deposit: Stratiform deposits deposits of Michigan, the historic Kupferschiefer deposits of Germany and Poland, and the important copper deposits of Zambia, research has demonstrated that the origin is similar to that of MVT deposits—that is, a hydrothermal solution moves through a porous aquifer at the base of a pile of sedimentary strata and,

The most important source of copper produced in the world in addition to porphyry copper deposits involves sediment-hosted stratiform copper deposits (SSC) [6,7,8,9,10].These deposits are characterized by variable resources in the range of 1.6 to 170 Mt (at 0.7–4.2% Cu), with a median of 14 Mt of ore (at an average grade of 1.6% Cu) calculated for 170 deposits [].

Apr 01, 1991  Stratigraphic and petrographic characteristics of the Creta copper shale deposit in the Flowerpot Shale of southwestern Oklahoma are compared with the betterknown Rudna deposit in the Kupferschiefer of south-western Poland. At Creta, early diagenetic mineralization is indicated by: (1) copper sulfide replacement of large spores and of pyrite, (2) lack of compaction of replaced spores

Formation of Sedimentary Rock-Hosted Stratiform Copper ...

Sedimentary rock-hosted stratiform copper deposits form by movement of oxidized, copper-bearing fluids across a reduction front that results in the precipitation of copper sulfides. Large-scale production of such oxidized fluids, as well as the formation of mobile hydrocarbons (oil) has probably been common since the formation of the first red ...

Abstract. Nomenclature for this class of sediment-hosted, Cu-dominated sulfide deposits is problematic. It has been variously described as, to name a few, sediment-hosted copper deposits (Edwards Atkinson 1986), stratiform copper deposits (Brown 1978), strata-bound copper deposits (Maiden et al. 1984), sediment-hosted stratiform copper deposits (Kirkham 1989), a subclass of stratiform ...

National mineral assessment tract GP04 - USGS

Copper deposits in this tract, characterized by the Flowerpot Shale, were assigned to the reduced-facies (shale-hosted or Kupferschiefer-type) model. The Flowerpot copper deposits are hosted by thin (10-50 cm), laterally continuous (as much as 20 km2) reduced shale beds associated with evaporites and red beds (Johnson, 1976).
