Abstract

Geochemical data is applied to clarify many geological questions. One of the practical operations of these data is statistical approaches. As it is recognized, the geological characters of many mineral deposits are performed with the use of Rare Earth Elements (REE) they have. The formation environment and physicochemical properties, specifically in vein type fluorite deposits, are pointed out by the REE content. Hayriye (Felahiye-Kayseri) fluorites are in the form of veins and epigenetically formed within the syenites in the Central Anatolian Crystalline Complex. The Felahiye fluorite mineralization is poor in REE contents. The average F% value of fluorite mineral taken from this region and analyzed is 19.72. When the arithmetic means of REE values are examined, Y has a maximum value with 20.65 and Lu has a minimum value with 0.006. In correlation analysis, a high positive correlation is observed between Tb-Er, Tb-Sm, Tb-Eu, Gd-Yb, Tb-Tm and Tb-Yb respectively. Regression analysis shows that the% F values are directly related to REE amounts.

Felahiye (Kayseri) Florit Yatağındaki NTE İçeriklerinin İstatistiksel Analizi

Abstract

Jeokimyasal veriler birçok jeolojik problemin çözümünde kullanılır. Bu verilerin etkili kullanım alanlarından biri ise istatistiksel yaklaşımlardır. Bilindiği üzere birçok maden yatağının jeolojik özellikleri ihtiva ettikleri Nadir Toprak Elementleri (NTE) yardımıyla yapılır. Özellikle damar tipi florit yataklarında oluşum ortamı ve fizikokimyasal özellikler REE içeriği ile açıklanır. Hayriye (Felahiye-Kayseri) floritleri Orta Anadolu Kristalen Kompleksinde siyenitler içerisinde damar tipi şeklinde ve epijenetik oluşumludur. Felahiye florit zenginleşmesi, Nadir Toprak Elementleri (REE) içeriği bakımından fakirdir. Bu bölgeden alınan ve analiz edilen florit mineralinin ortalama % F değeri 19.72'dir. REE değerlerinin aritmetik ortalamaları incelendiğinde, Y 20.65 ile maksimum, Lu ise 0.006 ile minimum değere sahiptir. Korelasyon analizinde sırasıyla Tb-Er, Tb-Sm, Tb-Eu, Gd-Yb, Tb-Tm ve Tb-Yb arasında yüksek pozitif korelasyon gözlenmektedir. Regresyon analizi, % F değerlerinin doğrudan REE miktarları ile ilişkili olduğunu göstermektedir.
