Troubles of Geo Thermo Baro Chrono Metry and of Paleo Piezo Metry

Zusatztext

This book presents the physical view on geological problems to quantify: the temperature and pressure of natural crystals´- minerals´, crystallization and polycrystalline aggregates´- rocks´/ores, formation - Paleo(Geo)ThermoBarometry; the value of the paleostress - PaleoPiezometry; the age of the objects - Geochronometry. It was shown that the traditionally used "classical" methods of Paleo(Geo)ThermoBarometry are incorrect. The known PaleoPiezometrical methods have some troubles too. We propose alternative original piezooptical methods for Paleo Thermo-, Baro-, Piezo- metry based on the discovered by me (1990) phenomenon "piezooptical crystals´ memory", which are practically free of the all described troubles. The discovered by us the natural separation of isotopes (2019) presents the real trouble for radiogenic isotope Geochronometry - at least for Rb/Sr- and Sm/Nd- methods. The separation is induced by gradients of temperature, and/or pressure (or deformation), which provide the corresponding diffusion processes, and can exist in the investigated object during all time of it´s life.The suitable objects for more correct radiogenic isotope Geochronometry should be found.
