The quartz is hosted by a vein-related shear zone and is associated with sulphide, sulphosalt
, carbonate and manganese oxide minerals.
In general, CCUK-15 most closely resembles a metallic sulfide or sulphosalt
In simplified form, the complex silver sulphosalt
minerals are dissolved by hot ferric chloride solution.
Locally, associated sulphosalt
minerals are: galenobismutite, cosalite, members of the bismuthinite-aikinite series (krupkaite-lindstromite range and gladite-hammarite range), argentian lillianite, Se-free junoite and members of the pavonite homolgous series.
Co-existing copper sulphides and sulphosalts
in the Abakaliki Pb-Zn deposit, Lower Benue Trough and their genetic implications.
Mineralisation consists of pyrite and arsenopyrite, sulphides of zinc and copper, antimonite, silver sulphosalts
and native gold.
Accessory chalcopyrite, tennantite, arsenopyrite, silver, barite and lead sulphosalts
also occur with the copper and barium phases tending to be most abundant in proximity to the Killoran and Derryville faults.
