Chemical evolution in the earth’s mantle and its explanation based on piezonuclear fission reactions

Abstract

The anomalous chemical balances at the major events in the geomechanical and geochemical evolution of the Earth’s crust should be considered as indirect evidences of piezonuclear fission reactions. Recent results observed at the scale of the Earth’s crust and reproduced at the scale of the laboratory during quasi-static and repeated loading experiments may be extended to the different layers of the planet like the atmosphere and the bulk Earth (mantle and external core). The mantle of our planet is characterized by very high pressures and temperatures (~150 GPa and ~4000 ˚C) that could favour this kind of reactions. In the present paper, it is shown that the most important chemical changes in the Earth’s crust evolution may be recognized also at the internal Earth’s layers. Recent investigations have shown that also the mantle is characterized by significant compositional time variations. This evolution may be interpreted in the light of the same nuclear reactions recently proposed to explain the chemical changes in the Earth’s continental crust and atmosphere through the entire life of our planet.
