Adjacent to the world-class Boliden deposit, fine- to coarse-grained Zn-Pb-Sb-Au-rich sulfide-sulfosalt-bearing horizons occur within the base of a metasedimentary succession that has previously been regarded to stratigraphically overlie the Skellefte Volcanics and Boliden deposit. The metasedimentary succession comprises interbedded mudstone and normal-graded crystal-rich volcanic sandstone-siltstone units, interpreted to be low-density turbidity currents in a subaqueous environment below wave ...

Abstract Orogenic gold mineralization in the Amalia greenstone belt is hosted by oxide facies banded iron-formation (BIF). Hydrothermal alteration of the BIF layers is characterized by chloritization, carbonatization, hematization and pyritization, and quartz-carbonate veins that cut across the layers. The alteration mineral assemblages consist of ankerite-ferroan dolomite minerals, siderite, chlorite, hematite, pyrite and subordinate amounts of arsenopyrite and chalcopyrite. Information on the ...

The Blue Dot gold deposit, located in the Archean Amalia greenstone belt of South Africa, is hosted in an oxide (± carbonate) facies banded iron formation (BIF). It consists of three stratabound orebodies; Goudplaats, Abelskop, and Bothmasrust. The orebodies are flanked by quartz-chlorite-ferroan dolomite-albite schist in the hanging wall and mafic (volcanic) schists in the footwall. Alteration minerals associated with the main hydrothermal stage in the BIF are dominated by quartz, ankerite-dolo...
