Abstract
ABSTRACTThe Palaeocene alluvial‐fan succession in central Anatolia, Turkey, contains three isolated zones of beekite‐encrusted clasts. Each zone is 3–5 m thick and c. 1 km long. Beekite is developed as thin (1–5 mm), concentric silica rings formed by replacement and encrustation of carbonate clasts. The formation of beekites requires a relatively long time, with non‐deposition and fluctuating arid/semiarid conditions. The significance of beekite is thus analogous to that of silcrete. The presence of beekite encrustation within the Palaeocene alluvial‐fan succession indicates considerable breaks in sedimentation in the eastern part of the basin, and this inference is supported by the lower thickness of the alluvium in the east.
