This study is about the mineralogical, petrographic
and geochemical investigation of the volcanic rocks around Şekerbulak that is about
40 km southeast of Ağrı province. Plutonic and volcanic rocks are observed in
the region. The plutonic units which is called as Taşlıçay Granitoid are in
tonalite, granodiorite, monzogranite and granite composition. Volcanic units consist
of the Yeltepe Trachyandesite and Yuva Riyoliti. These units exhibit
subalkaline, calcalkaline, high K series and shoshonitic features. In addition,
they exhibit enrichment in light rare earth elements (LREE) and large ion
lithophile elements (LILE). This enrichment is indicative of crustal
contamination.

Şekerbulak (Diyadin-Ağrı) Dolaylarında Yüzeyleyen Volkanik Kayaçların Mineralojik-Petrografik ve Jeokimyasal Özellikleri

Öz

Bu
çalışma, Ağrı ilinin yaklaşık 40 km güneydoğusunda yer alan Şekerbulak  dolaylarında yüzeyleyen volkanik kayaçların
mineralojik-petrografik ve jeokimyasal incelenmesini konu almaktadır. Bölgede
plütonik ve volkanik birimler gözlenmektedir. Plütonik birimleri tonalit,
granodiyorit, monzogranit ve granit türü kayaçlarda oluşan ve Taşlıçay
Granitoidi olarak tanımlanan granitoidler temsil etmektedir. Volkanik birimler
ise Yeltepe Trakiandeziti ve Yuva Riyoliti’dir. Bu birimler subalkali,
kalkalkali, yüksek K’lu seri ve şoşonitik özellik sergilerler. Buna ek olarak
hafif nadir toprak elementleri (LREE) ve iri katyonlu litofil elementler (LILE)
açısından zenginleşme gösterirler. Bu zenginleşme kabuksal kirlenmeyi işaret
etmektedir.
