摘要：
The article discusses new data obtained from mineralogical-petrographic, petrogeochemical, and isotopic-geochronological studies of the magmatic rocks of the Jerooy ore field, located in the western part of the Northern Tien Shan. The large Jerooy gold deposit of vein quartz-gold type is associated with the diorites of the Jerooy complex. Geochronological research findings (zircon U-Pb SIMS) revealed the age of magmatic crystallization of the diorites of the Jerooy complex, which host the gold mineralization, to be between 462 and 469 Ma, while the older Precambrian granites of the Tabalyk complex date to between 1160 and 1161 Ma. The article provides a petrochemical and geochemical characterization of the intrusive rocks involved in the geological structure of the Jerooy ore field. A model for the formation of the Jerooy deposit is proposed, and its geodynamic position is determined.
