In addition, the REE distribution patterns, Ce and Eu anomalies, La-Ce and La/Yb-EREE diagrams all suggest that the manganese deposit may have been formed in a passive continental margin with hydrothermal sedimentary affection. All the evidence above show that the manganese deposit has been formed in an ancient passive continental margin rift environment, it is the hydrothermal activities that provided the deposit with massive source material. This research may provide a new idea for the exploration of manganese deposits in Songtao County.
