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

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.
