These methods are frequently usedfor extracting the dimensional and physical parameters of the buried structures that stimulate gravity and magnetic fields. These estimates concern the location, local depth. strike, dip and physical quantity contrast, o.fpotentialfield contacts. We used results.from previous studies in order to correct the Bouguer data .for the gravity effect of the crust, The isostatic residual gravity anomalies, producedfrom the subtraction of the effect of the crust, are related to near-surfacefeatures. Noise suppression was achieved by slightly up- ward continuing the data by one cel! size. Geologic Significance of detected linea- ments is confirmed by comparisons with the known geology, active tectonics and seismicity as wel! as with topographic lineaments. Key words: Potentialfields. depth-to-source, lineaments analysis, seismotectonics. nEp iA'l4l'l IPJv r:p,,/(wia o.vr1 eipo.p,u6(ovjlc ,UE:eoJove; av6J..vuyjc; ypo.f!l.llKeVV (]TOIXE:l(J)V (]To.
