Abstract:

 Oreforming elements related to formation of different types of rocks are found with different kinds of ionic structures: those with the inertgaseous ionic structures generally enriched in the formation of sedimentary rocks, while those with the transitional or cupreous ionic structure are affinitive with the formation of magmatic rocks. Further researches indicate that various elements involved in the rock melting process are redistributed within and over the continental crust during the crystallization of crustal magma layer: the lithophile elements held the position of magma layer while the sulphophile elements moved to the cover of the layer, and the hydrophile elements migrated to hydrosphere while the atmophile elements to the atmosphere. Consistency of geological and geochemical structures of continental crust illustrated by the above processes reveals the unity between the microcosm and macrocosm of the natural world.
