The obtained numerous proofs of hot heterogeneous accretion of the Earth lead to a fundamentally new solution to the problem of magma genesis. According to these data, the Earth’s core was formed earlier than the silicate mantle as a result of the combination of iron particles of the protoplanetary disk under the influence of magnetic forces. The acid crust and Early Precambrian crystalline complexes occurred through the low-pressure bottom fractionation of the early magmatic ocean under the influence of increasing pressure loads formed during accretion of its upper parts. Mineralization of Early Precambrian crystalline complexes and early reservoirs were formed as a result of the release of emanations from the crystallized magmatic ocean. Magmas were formed by the frictional and decompression remelting of differentiates of the magmatic ocean.

Keywords: magmatic ocean, magma origin, Early Cambrian complexes.
