Abstract
The Shu-Ile suture is a unique and important geological structure of Kazakhstan. It is characterized by the presence of various intrusive formations and deep faults. The material composition of these intrusions is of interest for understanding the geological and metallogenic processes in this region. The data on petrographic and geochemical studies, geodynamics and tectonic activity are quite detailed, which made it possible to limit the level of correlation of igneous formations with the stages of their development. Based on the results of geochemical and petrographic studies of the material composition of intrusive complexes, their possible connections with neighboring geological structures and metallogeny of the region were established. The presented work is a definite contribution to the knowledge of the geotectonics and geodynamics of the Shu-Ile suture. Based on the data obtained, a conclusion was made about the origin and evolution of the intrusive complexes of the Shu-Ile belt, which may be important for further geological studies and forecasting of mineral resources in the region
