Nano-scale fracture phenomena and TeraHertz pressure waves as the fundamental reasons for geochemical evolution
TeraHertz vibrations and pressure waves are produced at the nano-scale in solids and fluids by fracture and cavitation, respectively. They present a frequency that is close to the resonance frequency of the atomic lattices and an energy that is close to that of thermal neutrons. Original experiments performed on non-radioactive rocks under mechanical compression loading have shown repeatable neutron emissions in correspondence to microand macro-fracture. After these experiments, a considerable reduction in the iron content of the crushed rocks appears to be consistently counterbalanced by an increase in Al, Si, and Mg contents. At the same time, significant measurements of neutron emissions are observed at the Earth’s Crust scale before and during seismic activity. In addition, several data coming from geochemistry and geomechanics have recently emphasized how tectonic activity should have been strictly connected to the most important changes in the Earth’s Crust chemical composition over the last 4.5 Billion years. On these bases, the hypothesis of a new kind of low energy nuclear reactions finds confirmation and could be considered as a valid explanation for the geologic evolution of the Earth’s Crust, Ocean, and Atmosphere. The same phenomenon appears to have occurred also in the chemical evolution of other planets of the Solar System like Mars, and of the Sun itself.
期刊介绍:
Strength, Fracture and Complexity: An International Journal is devoted to solve the strength and fracture unifiedly in non linear and systematised manner as complexity system. An attempt is welcome to challenge to get the clue to a new paradigm or to studies by fusing nano, meso microstructural, continuum and large scaling approach. The concept, theoretical and/or experimental, respectively are/is welcome. On the other hand the presentation of the knowledge-based data for the aims is welcome, being useful for the knowledge-based accumulation. Also, deformation and fracture in geophysics and geotechnology may be another one of interesting subjects, for instance, in relation to earthquake science and engineering.
