Abstract

Neo-Tetis Okyanusunun, Türkiye’nin kuzey kesiminde yitimi sonucunda İzmir-Ankara-Erzincan sütur zonu (IAESZ) gelişmiştir. Sutürlaşma sürecinin bitmesi sonrasında, IAESZ’nin her iki tarafı ve üzerinde gerilme ve magmatizma eş zamanlı olarak gelişmiştir. Bu dönem boyunca, Almus, Yıldızeli ve Yıldızdağ bölgelerinde yoğun magmatik aktivite gelişmiştir. Almus ve Yıldızeli bölgesindeki Orta Eosen magmatizması volkano-sedimentar birimler ile temsil edilmektedir. Buna karşın Yıldızdağ bölgesindeki gabroyik ve diyoritik kayalar magmatizmanın genel unsurlarıdır. Almus ve Yıldızeli bölgelerindeki volkano-sedimanter kayalar alt kesimlerinde sığ denizel sedimanter kayalar, orta ve üst kesimlerinde ise lav akıntıları ve volkanoklastik birimler ile temsil edilmektedir. Almus ve Yıldızeli bölgelerindeki eş zamanlı olarak gelişen magmatik birimlerin evrimini anlamak adına sekiz adet volkanosedimanter istif ölçülmüştür.
Her iki bölgede, stratigrafiye bağlı olarak üç farklı volkanik dönem ayırtlanmıştır. İlk evre amfibollü bazaltik andezit, andezit ve dasitlerden oluşur. İkinci evre bazalt ve piroksenli bazaltik andezitler ve üçüncü evre ise trakit ve trakiandezit dayk ve stoklarından meydana gelmektedir. Bütün bölgelerden elde edilen arazi verisi sonucunda orta-Eosen magmatik birimlerinin eş zamanlı olarak çarpışma sonrası dönemde geliştiği ve magmatizmayı tetikleyen olayın bölgesel ölçekte bir delaminasyon veya litosferik ayrılma süreçleri ile kontrol edildiği görülmektedir.

Volcano Stratigraphic Investigation of the Post-Collisional Middle Eocene Magmatism Around İzmir-Ankara-Erzincan Suture Zone (NE, Turkey)

Abstract

The obliteration of the Neo-Tethyan Ocean along the northern part of Turkey leads the development of the İzmir-Ankara-Erzincan suture zone (IAESZ). After the suturing stage; extension and magmatism concomitantly developed on the both sides and along the IAESZ during the middle Eocene. During this stage, the areas confining to Almus, Yıldızeli, and Yıldızdağ regions have experienced a severe magmatic activity. Middle Eocene magmatism in Almus and Yıldızeli areas are represented by the volcano-sedimentary successions. Besides, in Yıldızdağ region, gabbroic and dioritic intrusives are the dominant manifestations of magmatism. The volcano-sedimentary successions from Almus and Yıldızeli areas represented by shallow marine sedimentary units at the lower parts and lava flows and volcanoclastic units at the middle to upper parts. Eight volcano-sedimentary sections from Almus and Yıldızeli measured to demonstrate the evolution of the magmatic units developed coevally along the both sides of the suture zone. In both regions; three different volcanic episodes are differentiated based on stratigraphy. First episode includes amphibole-basaltic andesite, andesite, and dacite. Second episode contains basalt and pyroxene-basaltic andesite lavas and third episode represented by trachyte and trachyandesite dikes and stocks. The field data from the all regions demonstrated that middle Eocene magmatic units along the post-collision zone concominantly developed in a wide area and triggering of the magmatism controlled by the region-scale delamination and/or lithospheric removal processes.
