Abstract

Due to strong wall (exine) of the pollen grains, they can be well-preserved for a longtime in
the sediments. Therefore, palynology is especially a special tool for assessing paleovegetation and
paleoclimate throughout geological history. This study includes the late Miocene-early Pliocene
sediments for pollen analysis. The study area corresponds to Enez Lagoon, located in the Edirne area.
According to Enez pollen data, during the late Messinian (after Messinian Salinity Crisis)-early Zanclean,
the vegetation was mainly dominated by herbs (i.e., Poaceae, Amaranthaceae-Chenopodiaceae,
Asteraceae Asteroideae, Asteraceae Cichorioideae). Mesothermic trees are represented by deciduous
Quercus, Carya, Pterocarya, Zelkova, Fagus, Alnus, Betula, and Liquidambar orientalis. The abundance of
herbaceous plants during the late Miocene-early Pliocene indicates cold and dry climate in the area.

GEÇ MESİNİYEN-ERKEN ZANKLEYAN DÖNEMİNDE ENEZ (EDİRNE) YÖRESİNİN BİTKİ ÖRTÜSÜNDEKİ DEĞİŞİMLER

Abstract

Polen taneleri eksin olarak adlandırılan dış duvarının dayanıklı olması nedeniyle tortullar içerisinde
çok iyi muhafaza edilmektedir. Bu nedenle polenler jeolojik zaman boyunca meydana gelen vejetasyon
ve iklim değişimlerini tayin etmede önemli bir araçtır. Bu çalışma geç Miyosen-erken Pliyosen yaşlı
tortullarda yapılan polen analizlerinin verilerini içermektedir. Çalışma alanı başlıca Edirne ili’nde yer
alan Enez Lagününü kapsamaktadır. Geç Mesiniyen-erken Zankleyan’da (Mesiniyen Tuzluluk
Krizinden sonra), Enez polen verileri başlıca otsul bitki ekosistemleri (örneğin; Poaceae,
AmaranthaceaeChenopodiaceae, Asteraceae Asteroideae, Asteraceae Cichorioideae) ile temsil
edildiğini göstermektedir. Gölü çevreleyen yakın mesafede ise mezotermik ağaçlar yaprağını döken
Quercus, Carya, Pterocarya, Zelkova, Fagus, Alnus, Betula, Liquidambar orientalis gibi bitkilerden
oluşmaktadır. Geç Miyosen-erken Pliyosen’de Enez lagününde görülen otsu bitkilerdeki artış, bölgede
soğuk ve kurak bir iklimin varlığına işaret etmektedir.
