Adiyaman region is situated within SE Anatolian Fold and Thrust Belt which is a
part of Alpine-Himalayan Mountain Belt system. The Belt is evolved as Eurasian
plate and Arabian plate amalgamates in SE Anatolia. There are two main
contractional deformational periods, Late Cretaceous and Late Miocene, which are
followed by a strike slip deformation, during post-Late Miocene characterizing the
tectonics of SE Anatolia.
Series of folds and thrusts have a trend of almost ENE-WSW direction. The analysis
on bedding planes and folds shows around N70E trend. On the other hand, two
overthrusts that are closely linked to the folds and a sinistral strike-slip fault with
reverse component are differentiated. The overthrust belt with ENE-WSW trend
bounds the study area from north with a vergence from north to south and situated on
top of folded upper Miocene sequences. Another overthrust and a cross-cutting strike
slip fault with reverse component &ndash / Adiyaman Fault- form a &ldquo / pop-up&rdquo / structure
(positive flower structure) which is characteristic for in a transpressional regimes
manifested in geological cross-sections done from borehole correlations and seismic
sections.
To conclude, by combining the surface (field data) and subsurface data (seismic and
borehole data), the Alidag anticlinal structure that is formed along the Adiyaman
Fault are developed after the Late Miocene under transpressional regime.
