Polish sediment-hosted stratiform copper deposits associated with Zechstein sediments are one of the country’s most valuable natural resources and the basis for its copper
Read More1983-1-1 While the laterally extensive Kupferschiefer mineralization has long been considered the classic example of syngenetic stratiform copper deposits, many authors (e.g., Schouten, 1946; Rentzsch and Knitzschke, 1968; Rentzsch, 1974) have drawn attention to the diagenetic replacement textures showing pyrite replacement by copper-bearing sulfides in ...
Read More2012-1-1 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.

Read MoreThe article presents the prospecting strategy implemented by Miedzi Copper Corporation in search for new Cu-Ag ore deposits of the Kupferschiefer type. Sediment-hosted stratiform copper deposits in Poland occur mostly in the Fore-Sudetic Monocline, in the contact zone between the continental red beds (Rotliegend) and Zechstein marine sediments.

Nevertheless, sufficient occurrences are known of this very important geological type of deposit to suggest that some potential exists. Occurrences are widely distributed in rocks of many ages but the main ones are found in Carboniferous rocks of the Canadian Appalachians ...
Read MoreSedimentary 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 ...

Together, SSC deposits account for some 23 percent of the world’s Cu production and known reserves, as well as being significant sources of Co and Ag.
