The modern structural, drainage, and depositional systems of the Lake Hazar Basin in southeastern Turkey exhibit an "instantaneous" picture of faulting and sedimentation within an actively evolving pull-apart basin. A general sedimentation model is proposed which consists of two types of drainage and depositional systems. Streams entering the basin laterally cross numerous oblique-slip faults and are short, steep, associated with small drainage basins, and characterized by profiles with many knickpoints. They build alluvial fan deltas which are small, steep, and composed of coarse-grained debris flow and fluvial deposits. Fluvial deposits consist of braided channel and bar, sheetflood, and overbank facies. Streams entering the basin longitudinally flow along the surface trace of single faults and are long, gently-sloping, associated with large drainage basins, and characterized by smooth profiles. They build large, gently-sloping, alluvial fan deltas composed of fluvial and lacustrine deposits. Lacustrine deposits include shoreline, nearshore, and offshore facies. The relative relief of both systems is similar. The primary difference is gradient, which is controlled by position relative to the faults. This model is comparable with those proposed to account for sedimentation in ancient strike-slip basin deposits.
