Abstract:

The REE distribution in fluorites as an indicator of geologic-genetic features of ore deposits related to various magmatic associations was discussed. It was found that with an increase in the distance between the mineralization and the granitic massif or volcanic edifice, the relative Eu amounts in the fluorite increased and the negative anomaly gradually decreased, disappeared or even gave away to a positive anomaly. The analysis showed that when fluorites from deposits of various depths were compared, their Eu/Eu* ratio sinusoidally varied.
