 · Sandy dolomite This unit is 20 m thick and mainly composed of medium to thick-bedded sandy dolomite. The color of sandy dolomite is light yellowish to cream and reddish at places on fresh surface, and brown on weathered surface. The individual beds are 1.5-5 m thick. Planar cross-bedding is also observed in this unit (Fig. 3b).
