The geology and genesis of the Cerattepe volcanogenic Cu-Au-Ag deposit and its place in the geological development of the Artvin Volcanic Complex, Artvin, northeastern Turkey

摘要

The Late Cretaceous Artvin Volcanic Complex forms the eastern end of the Eastern Pontide Volcanic Belt, an ensailic, island-arc-type belt. A major feature of the Artvin Volcanic Complex is the Artvin Cauldron, a resurgent-type felsic cauldron. The recognition of the north-south-trending Cerattepe ore trend provides an important genetic link between the Cerattepe deposit, sub-economic porphyry Cu-Au mineralization hosted by the Fistikli sub-volcanic pluton, and other mineralization, such as the Sinkot volcanogenic massive sulphide (VMS) deposit. VMS mineralization formed during the late tumescent, the late resurgent, and the moat-and-ring-fracture stages of caldera development.
