Abstract

In this study, it is aimed to determine to petrograpgical, geochemistry and sources of the Yürekli volcanics (Biga Peninsula, NW Turkey). Tertiary volcanism is widespread in Western Anatolia (NW Turkey), is an important area where tectonic and magmatic events are observed together. Yürekli volcanic rocks composed of dacitic lavas and pyroclastics. Dacitic lavas show porphyric and hyaloporphyric texture, and consisting of plagioglase, quartz, amphibole, biotite, sanidine and Fe-Ti oxide minerals with apatite and zircon accessory minerals. Petrologically, it is high-potassic and calc-alkaline in characteristic. Yürekli volcanics show enrichment in large ion litophile elements (LILE) while depletion in high fi eld strength elements (HFSE) on the N-MORB normalized diagram. On the chondrite-normalized rare earth element (REE) plot, light rare earth elements are enriched but heavy rare earth elements are depleted in the rocks. Besides, REE patterns are concave shaped (mean $La_N$ / $Lu_N$ =16–25), and show a slight negative Eu anomalies (0.66–0.81). Plagioclase, amphibole and biotite fractional crystallization and crustal assimilation are important in the evolution of the Yürekli volcanics. According to all data, it can be argued that the Yürekli volcanics is formed in the post-collisional setting, and their parental magmas have derived from the melts of enriched lithospheric mantle.

Özet

Bu çalışmada Yürekli volkanitinin (Biga Yarımadası, KB Türkiye) petrografi si, jeokimyası vekökeninin ortaya konulması amaçlanmıştır. Tersiyer volkanizmasının yaygın olduğu Batı Anadolu(KB Türkiye), tektonik ve magmatik olayların berbaber gözlendiği önemli bir kuşaktır. Yüreklivolkaniti dasitik lav ve piroklastitlerinden oluşmaktadır. Dasitik lavlar, porfi rik ve hyaloporfi rikdokuda olup, ana mineral olarak plajiyoklaz, kuvars, amfi bol, biyotit, sanidin ve Fe-Ti oksit, talimineral olarak da apatit ve zirkon içermektedir. Petrolojik açıdan, yüksek potasyumlu ve kalkalkali karakterlidir. N-MORB’a göre normalize iz element diyagramında büyük iyon yarıçaplı litofi lelement (BİYE) içerikleri yönünde zenginleşme, yüksek çekim alanlı element (YÇAE) içerikleribakımından ise fakirleşme göstermektedir. Kondrite göre normalize edilmiş nadir toprak element(NTE) diyagramında; hafi f nadir toprak elementler zenginleşmiş, ağır nadir toprak elementler isedaha az zenginleşmiştir. Ayrıca nadir toprak element dağılım şekli konkav (ortalam $La_N$ / $Lu_N$=16–25)olup, zayıf negatif Eu anomalisi (0.66–0.81) gösterir. İncelenen volkanitlerin gelişiminde plajiyoklaz,amfi bol ve biyotit fraksiyonel kristallenmesi ve kabuk asimilasyonu rol oynamıştır. Elde edilen tümverilere göre, Yürekli volkanitinin çarpışma sonrası ortamda oluştuğu ve ana magma kaynağınınzenginleşmiş litosferik manto ile ilişkili olduğu söylenebilir.
