Abstract:   (2625 Views)

The Esfordi iron - apatite ore in Central Iran is
locAted in Bafq metallogenic province. Stratigraphically
most of the rock units belong to Precambrian and Cambrian
sequenses which the sedimentary and volcanic series are the
most spreading rock types and mineralization took place just
within the vOlcanic-sedimentary unit of the mentioned
series. Study of REE contents of apatite in Esfordi
iron-apatite orc shows high concentration of thClie elements.
Zonal distribution of some REEs, e.g. La, is identified
which varies from center to the rim of apatite ~ingle crystal.
Absence of negative Eu anomaly makes the Esfordi apatite
distinctive from the igneous types and may indicate a
hydrothermal origin for Esfordi apatites.
