Rare Earth Elements in Soils of the Central Forest State Nature Biosphere Reserve

Abstract The total content of rare earth elements (REEs) and the their oxalate-soluble fraction were studied in four soil profiles (Gleyic Umbrisols, Albic Gleyic Folic Retisols (Raptic), Dystric Retisol) Central Forest Nature Reserve. REE was normalized to a local standard (the Russian Platform clay), cerium europium anomalies quantified [8]. In addition initial redistribution REEs during formation rocks, soils undergo geochemical fractionation, which results depletion horizons heavy lanthanides europium. negative anomaly is maximal eluvial weaker or absent organic horizons. affects soils, also development positive some
