Western Boundary of East European Platform in Romania as Interpreted on Gravity and Magnetic Data

The geophysical detection of the western EEP boundary at crustal depths, south of the junction with the Carpathian Mts, represents an important geotectonic information when improving regional crustal models. Such geophysical and tectonic models are of great value in SE Europe, where the Vrancea seismogenic zone is generating high magnitude earthquakes at crustal and intermediate depths.

Satellite and ground Gravity and Magnetic regional data are integrated and interpreted in view of a better understanding of the TESZ southern continuation and location of the western EEP boundary.

The integrated interpretation of both satellite and ground Gravity and Magnetic data offers detailed information on the western boundary of the East European Platform at continental or regional scales.

The interpretation of gravity stripped map of Romania illustrated the EEP western boundary at crystalline basement depth and at lithospheric depth, respectively.

Based on the satellite magnetic and the gravity stripped maps, the eastern part of the Moesian Platform is interpreted to have geophysical EEP affinities (high magnetic properties and higher density) than its western part, the Intramoesian Fault being considered as a regional tectonic contact.
