The Sediment-Hosted Stratiform Copper Ore System One

Sediment-hosted stratiform copper deposits are the products of evolving basin-scale fluid-flow systems that include source(s) of metal and S, source(s) of metal- and S-transporting fluids, the transport paths of these fluids, a thermal and/or hydraulic pump to collect and drive the fluids, and the chemical and physical processes which result in

The Sediment-Hosted Stratiform Copper Ore System Open

Sediment-hosted stratiform copper deposits comprise disseminated to veinlet Cu and Cu-Fe sulfides in siliciclastic or dolomitic sedimentary rocks. Sediment-hosted stratiform copper deposits are extremely common though economically significant deposits are rare. They account for approximately 23 percent of the world's Cu production and known reserves in addition to being significant sources of

The sediment-hosted stratiform copper ore system

While understanding of sediment-hosted stratiform copper ore genesis at the deposit scale is relatively robust, there are still significant questions in regards its position in terms of basin evolution. A wide variety of basin architectures and processes can lead to the formation of sediment-hosted stratiform copper

(PDF) THE SEDIMENT-HOSTED STRATIFORM COPPER DEPOSIT

A close regional affiliation of sediment-hosted stratiform copper deposits with rift-basin evaporites and with low paleolatitudes where extensive evaporites may form under hot, arid surface conditions has been well established (Davidson, 1965;Glennie, 1989;.As the oxygen-rich brine circulates through deep, coarsegrained aquifers of the rift

Formation of Sedimentary Rock-Hosted Stratiform Copper

Glaciation may also be conducive for the formation of supergiant sediment-hosted stratiform copper deposits. Glacial periods correspond to magnesium- and sulfate-rich oceans that could have been responsible for additional sulfur in basinal brines developed during evaporite formation and would then be available during the long mineralization

Sediment-Hosted Stratiform Copper (SSC) Deposits

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

A hydrogeologic model of stratiform copper mineralization

Economic geologists have proposed and refined a model of district‐scale metal deposition that can account for many of the physical attributes common to many of sediment‐hosted stratiform copper deposits (Brown 1992, 1997). However, a generic model of basin‐scale cupriferous brine circulation remains elusive, and a vigorous debate

Relations between deformation and sediment-hosted copper

The first, main-stage mineralization, formed a classic sediment-hosted stratiform copper deposit during early diagenesis. Synsedimentary faults may have provided important conduits for cupriferous brines flowing from underlying red beds of the Copper Harbor Conglomerate into the reduced silts and shales of the Nonesuch Formation, where main
