Trace and Rare Earth Element geochemistry of the primary manganese ore from Bakony (Hungary)

Abstract

The aim of this work was the ore genetical investigation of the primary oxidized manganese ores in Bakony Mountains (Csárda Hill: Úrkút, Eplény) by the trace and rare earth elements. The main question was that the genetics of the primary oxidized manganese ores and the oxidized manganese ores in Eplény and in Csárda Hill are the same or not from the genetical point of view.
We calculated the enrichment factors of the trace and rare earth elements, the rare earth anomalies, the enrichment of the middle rare earth elements and the fractionation values of the rare earth element groups.
According to the parametres the primary oxidized manganese ores samples are of hydrothermal origin, although the rare earth element concentration of the waad samples is very high which refers hydrogenous origin with strong hydrothermal effect. The primary oxidized manganese ores (Csárda Hill, Eplény) are the same in genetical aspect.
