Mineralogy and geochemistry of Permian–Triassic lateritic‐bauxitic horizons, eastern and central Alborz, Iran: Implications for provenance, palaeogeography, and palaeoclimate
Abstract:This paper presents a survey of geological attributes on the lateritic‐bauxitic deposits to examine their provenance, palaeogeography, and palaeoclimate condition in the Permian–Triassic boundary of Alborz Mountain, north Iran. The mineralogical analysis revealed that haematite, quartz, goethite, kaolinite, diaspore, boehmite, and anatase are the major rock‐forming minerals in these deposits. The major oxide composition of samples detected that enrichment of Al2O3 (up to 31.5%) and Fe2O3 (up to 37.9%) led to t… Show more
