3D- and 4D-Modelling of the Hellenic Belt, Greece

Abstract

The updating of the Greek mineral deposit database and the available geological, geophysical and geochemical layers were used to construct 3- and 4-dimensional models of the most important Greek deposit groups that are located in Hellenic belt. Combining the different thematic layers of the GIS, different predictive maps were produced for specific types of ore deposits and specific commodities. The 3 and 4D geological models were produced for major epithermal gold deposits in the Rhodope zone (Perama and Aghios Demetrios) and the main sulphide mineral deposits (Olympias, Madem Lakkos/Mavres Petres and Skouries) in the Serbomacedonian zone, northern Greece. The 3D models were constructed in three different scales; deposit, semi-regional and regional. The 4D models demonstrate the main stages of the development of epithermal gold and polymetallic replacement deposits. The 3D models were built in gOcad and Gemcom Gems and the 4D models were built in gOcad and Midland Valleys MOVE.
