Abstract:
Purpose. To evaluate geodynamic processes of copper-ore deposits of the central and south-eastern regions of Kazakhstan which are spatially separated and different in genesis.
Methodology. We use the new U-Pb (zircon), Re-Os (molybdenite) dating and older K-Ar (biotite) data obtained from the use of the conditional analysis by biotite (K2O >7 %) only.
Findings. Based on the latest dating of rocks and ores of copper-porphyry deposits of Central Kazakhstan and Western Zhongar (China), a new model of the emergence and development of the copper-ore province is proposed.
Originality. A model of the origin and development of the Central Kazakhstan copper-ore province, uniting the fields of different origin, age and ore potential in a single ore-magmatic system is developed. The model of porphyry copper deposit formation (accumulation - transportation – sag) perfectly explains the different genesis of the Central Kazakhstan coeval deposits.
Practical value. Within the Central Kazakhstan copper-ore province it is necessary to conduct isotopic studies. Caldera ore magmatic system Besshoki is a priority object for a detailed study, based on the fact that according to statistics, about 85 % of copper-porphyry, and 100 % of copper-skarn ores occur either in magmatic rocks or in contact to them.
