Relationship of copper-molybdenum and gold minering with magmatism
Annotatsiya
In the investigated deposits, a combination of skarn and hydrothermal mineralization has been identified. Specific facies within intrusive complexes align with distinct postmagmatic formations. Skarn-magnetite formations are intricately linked with the granitoid complex of the initial phase, while hydrothermal mineralization has a genetic connection to the subsequent phase of magmatism, characterized by minor intrusions of granodiorite porphyry. A distinctive zonal structure of individual facies, such as quartz-sericite-chlorite metasomatites, is observed around these granodiorite porphyry intrusions. The manifestation of rock wall metasomatism, as well as copper-molybdenum and gold ore mineralization, closely corresponds to the extent of the granodiorite-porphyry occurrences. This correlation highlights the intimate relationship between the scale of mineralization and the manifestation of granodiorite-porphyry, emphasizing the role of specific magmatic phases in the formation of skarn and hydrothermal deposits. The findings contribute to our understanding of the geological processes governing the development of diverse mineralization types within these deposits.
