Ore geology of typical deposits in the Timok Cu-Au ore field, Serbia

The Tethys metallogenic belt is one of the three major metallogenic belts in the world. Porphyry deposits, epithermal deposits and skarn deposits are widely developed in this belt. The ABTS metallogenic belt is composed of Apuseni-Banat, Timok and Srednogorie ore concentration in the western part of the Tethys metallogenic belt. The mineralization is mainly related to calc-alkaline magmatic activity in the Late Cretaceous. Timok ore field is one of the ore fields with great economic significance in the ABTS metallogenic belt. It is of great significance to summarize the geological characteristics and metallogenic regularity of the deposit in this area for prospecting and exploration. Based on an overview of the geological characteristics of typical deposits in the Timok ore field, the metallogenic regularity and dynamic background of the ore field are discussed in this paper. The results show that the typical ore deposit in Timok ore field was formed between 88 Ma and 78 Ma, and the mineralization lasted only about 10 Ma. The mineralization age in Timok ore field also shows a trend of becoming younger from east to west. The typical deposit types in the ore field are mainly porphyry deposits (such as Majdanpek deposit, Veliki Krivelj deposit and Valja Strz deposit) and high sulfidation epithermal-porphyry deposits (such as Bor deposit and Cukaru Peki deposit), which are mainly Cu-Au mineralization. The differences in deposit types, mineralization characteristics and burial depth of ore bodies are caused by thrusting nappe structure and uneven denudation after mineralization. At the same time, the mineralization types of typical deposits and the change trend of depth of ore bodies in the ore field indicate that there are still great prospecting potential in the north-northwest of the ore field, the southeast of the Cukaru Peki deposit.
