Abstract
As a result of structural–geological and metallogenic studies and taking into account earlier works, it is established that the Oka ore district formed mainly in the Neoproterozoic–Early Paleozoic under conditions of tectonomagmatic reworking of cratonic terranes and allochtonous oceanic (ophiolitic) terranes over them. The reworking was initiated by island-arc, accretionary–collisional, and plume-related igneous complexes, which arose due to opening and subsequent closure of marginal structures pertaining to the Paleoasian Ocean. Active Middle and Late Paleozoic volcanic and plutonic processes gave rise to the redistribution of ore matter and formation of new mineral deposits.
