Özet

Western Anatolia has an extensional tectonic regime and the characteristics of the deformation in the continental crust observed in Aegean Region have a very complex structure. In our study area, the A degrees zmir city, Turkey, which is located within this active region, the general geological setting is also rather complex. This first microgravity study in A degrees zmir and its surroundings is related to the determination of active fault zones. It was conducted in the south of A degrees zmir, with the aim to investigate this complex structure in detail through microgravity data collected from six profiles throughout the survey area. The variation in Bouguer values was profoundly investigated along Profile P1 in N-S direction that was delineated to intersect all the tectonic elements. For this reason, Profile P1 was modeled in this study as 2D. As a result, the created gravity model was investigated together with geology, earthquake focal depths, and isostasy.
