Abstract
Karadeniz'in güney bölgesindeki 23 durak noktasında elde edilen karotlardan ahnan 62 örnekte Nannoplankton'-
lar incelendi. Örneklerde Emiliania huxleyi zonuna ait (NN 21-Holosen) oniki Nannoplankton türü tanımlandı.
Karadeniz'de 3000 yıl önce yaşamaya başlayan Emiliania huxleyi (Lehmann) türü sedimanlarda çok yaygın olarak
bulunmaktadır. Yapılan incelemede Karadeniz çökellerindeki Nannoplankton'ların yoğun olduğu seviyelerde uranyum
miktarının da arttığı saptandı. Alınan örneklerde, abisal düzlükte bulunan Emiliania huzleyi (Lehmann) yığışımlarındaki
uranyum oksit (U3O8
) miktarının diğer seviyelere göre yüksek olduğu belirlendi.

Abstract
Nannoplanktons obtained from sixty-two core samples taken from twenty-three holes penetrated in the Southern part of Black Sea were investigated in this work. Twelve species belonging to the Emiliania huxleyi zone (NN 21-Holocene) were determined. Emiliania huxleyi (Lohmann) came into existence in Black Sea three thousand years ago and is very abundant in these sediments. This study clearly showed that uranium concentration increases with increasing nannoplankton content of the sediments. It is also observed that the uranium oxide (U3O8 ) contents of the Emiliania huxleyi (Lohmann) accumulations on the abyssal plains are higher than those other sediments in the same environments.
