For the first time, the initial nature of the granulitis of the late Archarician South Deep Complex representing the Lower Non -Nicno formations of the south of the Aldan shield was established. Based on the geological data, the patterns of the distribution of the main Petro-gene elements and intxile elements, it is shown that the protolites of the granulitis of the South complex are lime-base volcanoes and mosquituity-toleite series, as well as terrigenous-ambulance breeds. Petroological models of the formation of the volcanic of lime--base and mosquititis of the-toleite series, based on the mechanism of plumovy tectonics, are proposed. For geochemists, petrologists and geologists involved in the study of metamorphic rocks
