Thybo H.; Ross A.R.; Egorkin A.V. (2003)Recent seismological studies have presented evidence for the existence of a layer with ultra-low seismic velocities at the core–mantle boundary at ca. 2900 km depth. We report high-amplitude, high-frequency, and laterally ...

Nielsen L.; Thybo H.; Egorkin A.V. (2002)Strong scattered arrivals are observed in the 800-1400-km offset range of the four Peaceful Nuclear Explosion (PNE) seismic sections along the 3500-km-long E-W-trending Russian profile Kraton. They give evidence of an ...

Egorkin A.V. (2003)The structure of the crystalline crust (CC) and the mantle was studied to a depth of 700 km by seismograms of chemical and nuclear explosions under kimberlite and oil and gas fields. Both types of fields are located in ...

UPPER MANTLE STRUCTURE BELOW THE DALDYN-ALAKITSK KIMBERLITE FIELD BY NUCLEAR EXPLOSION SEISMOGRAMS Egorkin A.V. (2001)It was established on the basis of seismograms of nuclear explosions that the upper mantle up to the depth of 410 km is characterized by chemical differentiation, which occurs as alternating layers with low and high body ...
