Abstract

The carbonate rocks of the Ruteh Formation, with a Permian age in the Majrouseh area (west of Urmia County, West Azarbaidjan province, northwestern Iran), host lateritic deposits. Mineralogical studies indicate that dolomite and calcite are the main mineral phases in these rocks, accompanied by smaller amounts of minerals, such as clays (kaolinite, smectite, and illite), hematite, goethite, siderite, K-feldspar, albite, and anatase. Based on the CaO/MgO ratio, their composition ranges from dolomite to slightly calcitic dolomite. Geochemical data show that the rare earth elements (REE; La–Lu) content of these rocks varies from 3.86 to 8.20 ppm, which falls within the range of marine carbonates. The Eu and Ce anomalies fluctuate in the range of 1.16 to 1.45 and 0.72 to 1.05, respectively.
