Volcanic redbed copper (VRC) deposits occur as concordant and peneconcordant disseminated and crosscutting vein and fault-controlled copper sulphide and/or native copper deposits in predominantly subaerial volcanic sequences. They are characterized by relatively simple copper sulphide and/or native copper mineral assemblages, contain variable amounts of silver, and are distinct from submarine, polymetallic, volcanic-associated massive sulphide base metal deposits. The name ‘volcanic redbed copper’ is used to draw attention to the similarity with redbed- and Kupferschiefer-type deposits in sedimentary sequences and to the fact that oxidized flow tops and some red interlayered sedimentary rocks are probably essential in the genesis of these deposits. In mixed volcanic and sedimentary sequences, sedimentary and volcanic redbed copper deposits occur together and, in places, no clear distinction can be drawn between the two deposit types.
