dc.description.abstract |
Rare earth elements (REEs) are currently the most strategic elements in the world due to
their significance in the diversified technological applications. Currently, a total of 478
million tonnes of REE resources is disseminated across the world, which is dominated by the
carbonatite deposits. The most common REE-bearing minerals found in carbonatites are
bastnaesite, apatite, monazite, allanite and parisite. In this regard, the Eppawala carbonatite
in Sri Lanka could be considered as a potential REE resource. The Eppawala carbonatite
occurs in high-grade meta-sedimentary and igneous rocks of the Precambrian Wanni
Complex as massive intrusions. In the Eppawala carbonatite, bed rock is mainly composed
of calcite (~90%), dolomite (5-9%) and magnesite (accessory carbonate mineral), whereas
chloro-fluor-hydroxyapatite, fluorapatite and carbonate-fluorapatite are present in a
secondarily developed phosphate-rich regolith. The Eppawala carbonatite is enriched of
REEs (~291-1962 ppm) with higher concentrations of LREEs. However, despite these
evidences, only a few REE prospecting studies have been carried out in the Eppawala
carbonatite. Therefore, detailed REE prospecting studies are recommended to discover the
full potential of this prospect, followed by development of suitable REE extraction processes. |
