Formation and Comparison of Rare Earth Element (REE) Geochemistry of Malatya Fluorite Deposits
Abstract
The fluorite deposits in Malatya (Turkey) region
are observed in Yeşilyurt and Kuluncak districts. Yesilyurt fluorites are
observed as vein type along the plane of unconformity between metamorphic rocks
on hydrothermal phase. Kuluncak fluorites are observed in the contacts of
alkaline syenites and marbles as vein type which the mineralization occured in
the pegmatitic phase as shown on Tb/La-Tb/Ca diagram. Yeşilyurt fluorites are
seen in purple, dark purple and blackish colors and Kuluncak is blue to purple.
When the geochemical characteristics of the Malatya fluorites are taken into
comparison, the Yeşilyurt region has 12.2-35.8% F values and Kuluncak has 15,
03-25, 42%. The REE contents of Kuluncak fluorites are richer than Yeşilyurt
fluorites as well as in Sr contents. In the (La/Yb)N-(Tb/Yb)N
diagram the Yeşilyurt fall into the field of New Mexico, however the Kuluncak
fluorites fall into the field of Akdağmadeni. The fluorite deposites are
compared on (Eu/Eu*)n–(La/Yb)n and Sc–ΣREE, (Tb/Yb)n–(La/Yb)n
diagrams. The Yeşilyurt fluorites display a distribution similar to the
Buyukkizilcik (Kahramanmaras) fluorites but Kuluncak fluorites spread in large
areas. The normalized-REE compositions of the Malatya fluorites exhibit
enrichment in LREEs compared to the HREEs. In addition the formation and
geochemical features of Malatya fluorites differ from each other.
