New data on the structural–hydrodynamic organization of the ore-forming system (OFS) of the Irokinda deposit in the architecture of deep-seated faults are presented. The specific features of OFS functioning in a "centroid" seismic stress field under abnormal pressure exceeding the lithostatic one are revealed. The area of OFS feeding from autonomous polygenetic sources, which formed polychronously in tectonomagmatic pull-apart structures, is outlined for the first time. A 3D model of polygenetic source formation in one of the structures was created. A model of OFS functioning during the post-collisional period is discussed. According to this model, centroid-type paleoearthquakes with hypocenters in the Benioff zone periodically opened reservoirs with metamorphogenic gases, accumulated in an accretionary prism, and provided their transfer into pull-apart structures, mixing with magmatogenic fluids and migration of mixed gas hydrates into the mineralization zone.
