Teisseyre-Tornquist tectonic zone: some interpretative implications of recent geological and geophysical investigations

Abstract

On the basis. of the borehloIe data, explosive seismic investigations and head flow measurements, the character of the Teisseyre-Tornquist zone is suggested as a pulsation crustal depression, the origin, of which is associated with the eclogite-basaIt phase changes within the "Moho layer". Because of that the Teisseyre-Tornquist zone cannot be regarded to be a hidden intracontinentaI rift or aulacogen.
