| dc.description |
The East Pontic metallotect represents a Jurassic to Miocene island arc system hosting a great number of strata-bound and stratiform volcanogenic massive sulfide deposits, i.e. Murgul, Madenkoy and Lahanos which occur in a strongly altered dacitic to rhyolitic Upper Cretaceous (Senonian) pyroclastic rocks. The mineralization is related to the first stage of phyllic and argillic alteration showing poor mineralization of disseminated pyrite and chalcopyrite and the second stage of silicic alteration is distinguished by commercial stockworks and small ore lodes. The deposits of Madenkoy and Lahanos in the western part of the metallotect are related to a submarine volcanic activity in a volcano-sedimentary sequence under temporarily subaquatic conditions and represent Kuroko-type deposits. In comparison, the Murgul deposit in the eastern part can be assigned to a subvolcanic-hydrothermal origin with an island arc volcanism under subaerial conditions and forms a transition from Kuroko-type deposits to copper porphyries genetically (Murgul type). |
