(a) General stratigraphic column of the eastern Alborz Mountains (modified after refs.14,20), and (b) local stratigraphy showing B-type bauxite lenses and horizons between carbonates of the Elika Formation and shale and sandstone of the Shahmirzad Formation (Shemshak Group) in the Jajarm deposit, North Khorasan Province, northeastern Iran. A = early Cimmerian unconformity; B = main Cimmerian unconformity.
