Results were revealed that, mineralogically, the carbonate rocks in the Tayiba Formation are mainly composed of calcite, dolomite, quartz and clay minerals. The terminal parts of the studied Tayiba Formation are more dolomitized relative to the middle beds. Geochemical analysis revealed that the carbonates of Tayiba Formation were deposited under shallow, oxidizing, marine environment. The dolomitization process has taken place in marine environment. Carbonate rocks of the Tayiba Formation are highly enriched in trace elements and highly to moderately rare earth elements. The studied carbonate rocks characterized by light REE (LREE) enrichment than heavy REE (HREE).
