摘要
The tectonic setting for the area around the Arabia-Africa-Anatolia triple junction is described from combined Landsat-SPOT satellite image analysis and field observations. Since the Late Miocene the motion along the East Anatolian Fault generated major structures corresponding to shortening with a sinistral-slip component. The 150 km wide area of the triple junction is highly deformed by folding and thrusting, distributed mainly on the border of the Anatolian block. In addition, kinematic reconstructions confirm that the Arabia-Anatolia relative motion is both sinistral and convergent. The sinistral strike-slip faults of the East Anatolian Fault zone are of second-order and local consequences of the N-S Arabia-Anatolia collision.
