Abstract

A series of entrenched, deep-water slope-channel complexes form a planform tributary network of conduits on the northern slope of the Eocene-Oligocene back-arc Elazig Basin in eastern Turkey (Figures 1—3). The lower part (60%) of the channel complex fills are characterized by coarse-grained sediments and the upper 40% by heterolithic facies (Figure 4). The heterolithic facies drape a synsedimentary faulting phase of activity that saw a reactivation of the channel complexes after filling. The lower part of this facies, which thickens over the channel-complex axes, is dominated by slumped shales and local, thin-bedded turbidite sandstones and siltstones. The upper part comprises sheet and lenticular pebbly sandstones and sandstones, interbedded with rippled sandstones and siltstones, associated with channelized geometries (Figure 5A, B). This interval is also characterized by lateral accretion surfaces, where beds have an asymptotic and shingling character, an association with sedimentary structures such as trough cross-bedding, and where paleocurrents suggest sinuosity of the channel elements. The sinuous channels are up to 3 m (10 ft) thick and 10-40 m (33-131 ft) wide. Interleaving shales have abundant and diverse deep-water and shelfal ichnofacies, and deep-water benthic/plank-tonic foraminiferal assemblage ratios. The sand-prone portions of these sinuous channel bodies are dislocated and usually confined to the accretionary margins and channel floors. The channel elements can be tracked for 7 km (4 mi) in a series of sections above four separate, entrenched, deep-water slope-channel complexes. These late-stage sinuous channel elements and their association with larger, longer-lived, and persistent (i.e., entrenched), deep-water slope-channel complexes are documented for the Main channel.
