Abstract

The tectonic regime of Eastern
Anatolia is determined by Arabian-Eurasian continentcontinent convergence and
the mechanism occurred with the convergence. North Anatolian Fault Zone (NAFZ),
Eastern Anatolian Fault Zone (EAFZ), North Eastern Anatolian Faults and Bitlis
Zagros Suture Zone are formed by this convergence, represent the characteristic
of lithospheric structure of the region. In the scope of this study, the gravity
anomalies of Eastern Anatolia were used for investigating the lithospheric
structure. Firstly, second order trend analyses were applied to gravity data
for examining the characteristic of the anomaly. Later, the vertical and
horizontal derivatives methods were applied to the same data. Generally, the
purpose of the applying derivative methods is determining the vertical and
horizontal borders of the structure. Therefore, this method gives the opinion
about the characteristic of the lithospheric structure of the study region.
According to the results of derivative methods, the structure transitions were
increased rather especially with Bitlis Zagros Suture Zone. At the last step,
the gravity studies were evaluated together with the seismic activity of the
region. Consequently, the geodynamical structure of the region is examined with
the previous studies done in the region.
