Application Of The Porphyry Copper/Polymetallic Vein Kin Deposit System To Mineral-Resource Assessment In The Mátra Mountains, Northern Hungary

The application of the tectonic model for the porphyry copper/polymetallic vein kin-deposit system, proposed by the authors and used to assess the undiscovered metallic mineral resources of northern Hungary, is illustrated here for the Matra Mountains, northern Hungary. This model is based on the evolution of strain features (duplexes and flower structures) developed in the strike-slip fault systems in continental crust above a subducting plate and the localization of mineral deposits within them.The application of this model relied on the integration of data from the literature, satellite images, and geologic maps. During the time of the mineralization (15-16 Ma), the regional-scale tectonic framework was dominated by a right-lateral, pull-apart structure cored by the Mátra Mountains volcanic complex. While synthesizing these data, it was found that the tectonic elements identified on the satellite images could be closely associated with the location of the vein mineralization discovered in the Mátra Mountains. Displays are presented that illustrate how the individual tectonic and geologic elements (faults, volcanic rocks, and sedimentary basins), as well as the relation of the mineralized structures to the complex array of extensional and shear faults that are created inside of a strike-slip fault duplex, are associated.
