Abstract

Low-frequency seismic reflection investigations of the lithosphere were conducted in SE Hungary during 1992. The profile PGT-4 starting at the eastern flank of the Algyo High crossed the: Hodmezovasarhely-Mako Graben; the Pusztafoldvar-Battonya Ridge and the Bekes Basin. Integrated interpretation of seismic, regional geothermal, geomagnetic and gravity data reveals an elevation in the lower crust, the crust-mantle and the lithosphere-asthenosphere boundary, as well as magmatic intrusions which protrude as high as the upper crust beneath the Bekes Basin. Deep reflection and magnetotelluric data along the PGT-4 indicate an anomalous rise of the lithosphere-asthenosphere boundary beginning at the NE termination of the profile. Beneath the Hodmezovasarhely-Mako Graben both the crust-mantle and the lithosphere-asthenosphere boundaries form a minor uplift slightly westward from the Hodmezovasarhely-Mako Graben. Low-frequency seismic reflection measurements within the Carpathian Basin outline a sketch of the complete lithosphere, suggestive of tectonic development described by low angle extensional basin forming models.
