Volcanogenic Deposits of Non-ferrous Metals in the Lesser Caucasus and Eastern Pontides
Volcanogenic Deposits of Non-ferrous Metals in the Lesser Caucasus and Eastern Pontides DOI: https://doi.org/10.30564/jgr.v3i4.3572 Abstract The paper presents brief characteristics of geological environments of ore deposit occurrences in Turkey, Georgia and Armenia. They can be attributed to Kuroko-type deposits, being distinguished by the character of ore accumulation. To the west, in Turkey, there are epigenetic and hydrothermal-sedimentary copper-zinc deposits that were formed in deep restricted basinal settings. An example of the latter is the Chayeli deposit. To the east, in the Caucasus, we have predominantly only epigenetic deposits. Besides, in the Bolnisi mining district (Georgia) there is the Madneuli deposit which represents an example of polyformational deposit. Here, within the restricted territory, have been concentrated: barite, barite-polymetallic, gold-bearing secondary quartzite, large-scale...
