The origin of the low density zones in the crystalline crust of the Transcarpathian depression (Ukraine) from petrophysical thermobaric modelling
Purpose. Based on laboratory PT-studies of rocks and their joint analysis with the data from the regional profile RP-17, the aim of this research is to reveal the origin of the low-velocity zones in the Transcarpathian depression as zones of thermobaric rock decompaction and to elucidate the relationship of these zones with earthquakes and hydrocarbon fields. Methodology. The essence of such an approach is the comparison of the DSS information with experimental data on the physical parameters of rocks at high pressures and temperatures.
