By Pär Weihed

This booklet offers the result of the key european undertaking Promine. For the 1st time there's now a ecu database to be had on mineral deposits, in addition to 3D, 4D and predictive types of significant mineral belts in Europe: Fennoscandia (Skellefteå and Vihanti-Pyhäsalmi), the Fore-Sudetic basin (Kupferschiefer deposits in Poland and Germany), the Hellenic belt in northern Greece, and the Iberian Pyrite belt and Ossa Morena area in Spain and Portugal. The ebook additionally describes the modelling recommendations utilized and the way varieties of software program are used for 3- and 4-dimensional modelling. moreover, basic descriptions of the way to construct the database constitution of three-d geological information are supplied and either 2nd and 3D predictive types are provided for the most mineral belts of Europe.

This temporal extension may be related to the palaeogeographic domain (Gondwana margin undergoing fragmentation during Cambro-Ordovician), distinct from the European terranes and where pre-concentrations had possibly occurred. Some areas, such as massive sulphides domains, also show relatively high favourability and should be investigated in more detail. Gallium Only 39 deposits in the ProMine MD database contain gallium. 26). 7) is notable. Also, gallium-bearing deposits are commonly enriched in germanium (74 %) although the opposite is not necessarily true (25 %).

Some Fe (Fe–Cu) IOCG style deposits are identified in the Ossa Morena Zone in southwestern Iberia. They are mesozonal albitite-related magnetite deposits and are interpreted (Tornos et al. 2005) as being related to either residual melts of rift-related juvenile magmas (Cambrian) or anatexis of earlier mineralization during high T/low P metamorphism along major shear zones of Variscan age. Group 07: Mafic intrusion (Fig. 5b) Theoretical commodity association: Fe, Ti, V This type of deposit is clearly associated with Precambrian rocks in the Fennoscandian Shield, with groups varying in age from one district to another.

Cassard et al. of deposits in favourable lithologies. 16 potential maps were thus produced (Fig. 5). The importance of this methodical approach is that it could be used whatever the type and the density of deposits over large areas and yields consistent results at continental scale. The mineral potential maps are presented and discussed below. They show how the continental scale distribution of known mineralization derived from the ProMine MD database is consistent with the regional geological and tectonic context.
