Rare earth elements (REE) and isotope composition (δ
The rare earth elements (REE) geochemistry and the isotope (δ13C, δ18O) composition of manganese ores of the Chiatura (Georgia) deposit were studied. One of the major features of all types of manganese ores is negative cerium (Ce/Ce*PAAS) anomaly and the absence of europium (Eu/Eu*PAAS) anomaly. Oxide oolitic manganese ores …
