On the relationship of Moon composition and the primary Earth's crust and mantle

Abstract

In this paper we propose a concept that is based on the idea of a two-stage mechanism for the formation of planets. In the first stage it was formed the primary planetary embryos the central part of which is composed of material similar in composition to the Allende meteorite inclusions SAI. The middle part is composed of iron and external part - of material close to the enstatite chondrites. Under the proposed model, the substance formed the central part of the Moon, separated from the material of the Earth in the first stage of its formation during the collision and destruction of its primary embryos. In this case, the bulk of iron moved into new nuclei of the early Earth, and a significant proportion of refractory elements have been thrown into orbit, where the Moon was formed.
