Isotope Chronology of Geological Processes
2019The chapter presents new geochronologic results of various isotope techniques (U–Pb SIMS and Re–Os TIMS) along with their comparison with already published data. The main intrusions of the Norilsk district are demonstrated to be emplaced almost simultaneously with two possible magma intrusion pulses at 254 ± 4 and 244 ± 4 Ma (U–Pb SIMS), assuming c. 10

Monitoring Endogenic Geological Processes
2007Among the most effective and successful environmental observation systems are those operated in Japan, China, the USA, and USSR-Russia. These use a complex of mutually supporting techniques to secure information on seismically dangerous structures and territories (GPS, laseraided telemetric measurements, high-altitude aero-geophysical surveying ...

GRAVITATIONAL GEOLOGICAL PROCESSES (KARST)
Crisis Management and TechnologiesThe article presents karsts, as one of the gravitational geological processes, developing in rocks (limestone, dolomite, gypsum, anhydrite, sodium and potassium salts) dissolving in natural surface and groundwater. For the first time, an attempt was made to study karsts, changes in hydrogeological conditions during their development and the influence ...

Fluids in geological processes
1994The role of fluids in the Earth’s crust and mantle has been a subject of debate by penologists, geochemists and geophysicists for much of the present century, and an extensive literature exists in both English and Russian.

Titan's global geologic processes
2016We have mapped the Cassini SAR imaged areas of Saturn's moon Titan in order to determine the geological properties that modify the surface [1]. We used the SAR dataset for mapping, but incorporated data from radiometry, VIMS, ISS, and SARTopo for terrain unit determination.
