The Sediment-Hosted Stratiform Copper Ore …
Sediment-hosted stratiform copper deposits were described by Gustafson and Williams (1981) in the Economic Geology 75 th Anniversary Volume. Work conducted through the 1970s and 1980s was compiled by Boyle et al. (1989) in the Geological Association of Canada volume entitled Sediment-Hosted Stratiform Copper Deposits.

Sandstone copper, shale-hosted copper, redbed Cu, continental redbed, Kupferschiefer type, marine paralic type, reduced facies Cu, Revett Cu. DESCRIPTION Sediment-hosted copper deposits are stratabound, that is, they are restricted to a narrow range of layers within a sedimentary sequence but do not necessarily follow sedimentary bedding. They are epigenetic and diagenetic, that is, they are ...

Stratiform Deposits mineral deposits concentrated within one or more strata of volcano-sedimentary and sedimentary bedded rock formations. The most characteristic examples are deposits of lead and zinc ores in strata of carbonate rocks (the Missouri Valley deposits in the USA and similar deposits in the USSR, Canada, Poland, Austria, North Africa, and ...
SEDIMENT-HOSTED DEPOSITS
Sediment-Hosted Copper Deposits “Epigenetic” disseminated Cu deposits hosted in reduced sedimentary rocks. 3. Sedimentary-Exhalative (SEDEX) Type Deposits “Syngenetic” stratiform, bedded Zn-Pb deposits hosted by fine-grained clastic sedimentary rocks. These three types may be considered as a spectrum of base-metal ore deposits which form in sedimentary rocks at some time during the ...

It hosts one of the world’s greatest concentration of stratiform copper–cobalt deposits, representing more than half of the world’s mineable cobalt and includes world-class Cu–Co deposits, e.g. Kolwezi, Tenke-Fungurume, Konkola-Chililabombwe, Nchanga, Nkana, Mufulira, each containing ⩾10 Mt copper. Total copper hosted in the Katangan basin of central Africa is close to 200 Mt if sub ...

Stratiform copper mineralization is hosted by gray to black shales and siltstones of the basal Nonesuch Formation. Copper mineralization is overlain by laminated gray siltstones of the Nonesuch Formation and is underlain by red-bed sandstones, conglomerates, and minor siltstones of the Copper Harbor Formation; these rocks are part of a thick section of clastic sedimentary rocks that comprise ...
ON STRATIFORM COPPER DEPOSITS OF CHILE (*)
Stratiform copper deposits are abundant in Mesozoic and Cenozoic volcanic and sedimentary rocks of Chile and, in some way, are related to calc-alkaline volcanism that has been active in this region during both Eras. There are also stratiform deposits of manganese, of Paleozoic, Cretaceous and Pleistocene age, wich are also related to volcanism, and iron deposits of Paleozoic and Pleistocene ...

Copper shale mining in Germany: Kupferschiefer …
Copper shale mining in Germany dates back to the year 1199. According to legend, the miners Napian and Neuke found a new deposit on "Copper Mountain" near Hettstedt, east of the Harz Mountains and they started to mine it. 80 million years ago tertiary tectonic movements led to the formation of the Harz Mountains moving the copper shale layers to the surface, creating places bountiful in copper ...
