Summary:The general characteristics and age of the epi-ophiolitic sedimentary cover of the Sarikaram ophiolite, central Anatolia, are described, and illustrated with a simplified geological map with a summary of the petrography, geochemistry and tectonic setting of the ophiolite, which represents the oceanic crust of the Central Anatolian Ophiolites. The lower section of the ophiolite is composed of gabbros faulted against a sheeted dyke complex merging up-section into basalt lavas and breccias. The gabbros are intruded by trondhjemitic plagiogranite related to high-level rhyolite dykes and sills which traverse the upper volcanic part of the ophiolite. The sedimentary cover consists of epiclastic volcanogenic deep-sea sediments and debris flows intercalated with pelagic units. The last-named are dated by foraminifera as early-Middle Turonian to early Santonian, and indicate rifting in a marginal sea adjacent to a volcanic arc. [R.K.H.]
