Density model of the Earth crust of the Ukrainian Carpathians along the PANCAKE profile

The purpose of the work is the analysis and geological-tectonic interpretation of the anomalous gravity field of the Ukrainian Carpathians and adjacent territories, as well as the construction of a density model of the Earth's crust and upper mantle according to the international PANCAKE seismic profile. The need to build a density model along the PANCAKE profile is due to the significant interest of a number of geologists and geophysicists in the results of seismic research along this profile. It is also caused by certain discrepancies in the seismological models of different authors.

On distribution of earthquakes relative to the density boundary in stratification of Earth’s crust (case study in selected areas of the North-East of Russia)

Purpose. Identify patterns in position earthquake hypocenters relative density stratification in the borders of the earth's crust. Methods. The methods of the new interpretative gravity anomalies by interpreting the gravity field is determined by the power of the earth's crust, forming the anomaly in the gravity field (Bouguer). In this border area forms a surface that separates two sector of the earth's crust. In its upper part, in the sector above the fixed surface, observed density change substance at the transition from one block to another in the horizontal direction.
