  • Major Mines & Projects Arcturus Mine

    The Arcturus gold mine, located within the Shamvaian Group, is hosted in the Iron Mask Formation, which comprises a succession of metamorphosed felsic volcanics and associated metasediments including prominent bands of sulphide-facies iron formation, phyllites, meta-arenites, and quartzose schists (Oberthur et al., 2000). The mineralized shear zones in the Arcturus mine are characterized

  • Geology of Zinc Deposits MVD

    I consider the lead and zinc deposits of the Mississippi Valley to be the result of descending waters. There are many features that we have not determined and yet when you see the general field relations, it seems to me that the cause and effect can be well explained by descending circulation. In the Joplin-Miami district, for instance, the ore deposits are connected with openings or with old

  • Geology and origin of the Century Zinc deposit

    The Century deposit represents an important new genetic variation of the style of sediment-hosted Zn-Pb-Ag mineralisation that is so well represented in the Mount Isa Inlier and McArthur Basin of north-eastern Australia. The deposit is hosted by shale and siltstone of the Mesoproterozoic age Lawn Hill Formation. Mineralisation comprises fine-grained sphalerite with minor galena and pyrite.
