    Fulltext :

    The geological surveys of Finland, Norway, Russia and Sweden have set up the Fennoscandian Ore Deposit Database (FODD) covering the entire Fennoscandia (Fennoscandian Shield and the Caledonides). The FODD presents a set of key features, according to uniform guidelines, of mined and unexploited deposits in the region. The database is in public domain in the Internet (http://en.gtk.fi/ExplorationFinland/fodd/).
    It now contains information on 293 mines and deposits in Finland, 154 in Norway, 237 in Russia, and 260 in Sweden. In addition, a Fennoscandian deposit map was published in early 2008. The data fields in the FODD include information on location, mining history, tonnage, commodity grades, geological setting, age, ore mineralogy, style of mineralisation, genetic models, and sources of data. Guidelines for each data field are defined so that the same feature is described by the same key word(s) across the entire region. The following metals are included into the FODD: Ag, Au, Be, Co, Cr, Cu, Fe, Li, Mn, Mo, Nb, Ni, Pb, Pd, Pt, Rh, REE, Sc, Sn, Ta, Ti, U, V, W, Y, Zn, and Zr.
    Only such deposits are included where one or several of these metals together form the majority of the value of the case, and only when there is a resource estimate of some kind for the deposit. In the database, deposits are classified into size categories according to their total metal content. This classification is based on whatever in situ figures there are available for a deposit. Hence, the data for most of the cases are not compliant with the modern international standards of mineral resource reporting (e.g., the JORC code).
    The FODD is set up as a tool for both exploration in northern Europe and for research in economic geology. It is also hoped for that the database would serve as a tool for political decision making, to give an idea of the mineral wealth and of the importance of the mining industry to our countries, and make the region even more attractive for investment. The FODD is set up so that one can easily constitute tables and draw maps according to, for example, main metals, deposit sizes, existing and closed mines, or pick up unexploited large deposits, mines in production, deposits in certain subarea or in rocks of certain age, see regional indications of exploration potential, etc.
