FILTRATION OF WEST ANATOLIAN BOUGUER ANOMALIES AND INVESTIGATION OF THE THICKNESS DISTRIBUTION OF THE CRUST

Abstract

Two dimensional low-pass filters were used to prepare West Anatolian Bouguer gravity maps for interpretation. Talwani method was applied to the profiles obtained from appropriate directions of the regional Bouguer gravity anomaly map, and West Anatolian crustal thickness geometry has thus been modelled. West Anatolian crustal thickness starts at 30 kms in the north at the Black sea coast and increases to 35-40 kms at the Lake District (Isparta-Turkey). The thickness decreases to 32 kms at the Mediterranean coast. In the West-East direction the crust starts with 32 kms at the Aegean coast and increases to 40 kms towards central regions.
