Relevance. The metallogeny of the Yenisei Ridge has established a high degree of age correlation between the stages of its lithospheric evolution, expressed in granitoid magmatism, and all the milestones of the gold-ore process. At the same time, modern scientific and industrial literature contains significantly divergent taxonomic categories for describing granitoid magmatism in the Yenisei Ridge and, in particular, within the Verkhne-Yenashiminsky Ore Cluster. Such discrepancies create significant difficulties and generate uncertainty in classification, dating, and genetic attribution of individual complexes to specific geodynamic events. As a result, it becomes considerably problematic to trace the connection between the metallogenic development of specific areas and ore clusters with the granitoid magmatism manifested in their vicinity. In this regard, an urgent task is the analysis of existing classification schemes with subsequent certification of granitoid massifs based on the following factual foundation: available data on petrographic composition and geochronology, and the characteristics of their manifestation in radiogeochemical fields, reported here for the first time. Aim. Radiogeochemical certification of the granitoid massifs of the Verkhne-Yenashiminsky Ore Cluster based on airborne gamma-ray spectrometric survey data. Methods. Analysis of complex geological and geophysical materials using radiogeochemical indicators. Results and conclusions. The paper introduces the detailed description of the currently existing classifications of granitoid magmatism in the Trans-Angara region and their correlation with each other. Based on the analysis of airborne gamma-ray spectrometric data, a contrasting radiogeochemical difference was established between the Verkhne-Yenashiminsky Ore Cluster granitoids formed in different geodynamic settings: rift-related complexes (Glushikhinsky, Gurakhinsky) and late-collisional Kalamin-type granitoids. An intermediate position between them is occupied by the granitoids of the Ayakhtinsky complex, which have the most controversial interpretation of their nature. The authors identified high post-magmatic mobility of radioactive elements (U, Th, K), especially for the rift-related complexes. It was established that airborne gamma-ray spectrometry is an effective method for differentiating granitoid complexes. The wide radiogeochemical diversity of the Verkhne-Yenashiminsky Ore Cluster granitoids reflects the complex, multi-stage geodynamic evolution of the region and is an indicator of its high metallogenic potential.
