δ18O and δ13C stable isotope data from a new composite sediment record, Cyprus (Eastern Mediterranean)@en

We present a c. 12 Ma record of oxygen and carbon stable isotopes from the Island of Cyprus to help constrain the nature and extent of Miocene palaeoceanographic changes in the eastern Mediterranean region. Cyprus includes Neogene deep-sea pelagic sedimentary rocks, which are suitable for stable isotope studies. Our composite geochemical record integrates data from the Lower-Upper Miocene succession at Kottaphi Hill along the northern margin of the Troodos ophiolite, and the Upper Miocene succession at Lapatza Hill to the south of the Kyrenia Range. Calcareous nannofossil biostratigraphy reveals that the composite record spans the Miocene Climatic Optimum's onset to the beginning of the Messinian Salinity Crisis.本研究提供了取自塞浦路斯岛的约12 Ma（百万年）氧、碳稳定同位素记录，以期约束地中海东部地区中新世古海洋变化的性质与波及范围。塞浦路斯岛发育新近纪深海远洋沉积岩，适宜开展稳定同位素研究。本研究的复合地球化学记录整合了特罗多斯蛇绿岩北缘科塔菲山的下中新统至上中新统地层序列数据，以及凯里尼亚山脉以南拉帕扎山的上中新统地层序列数据。钙质超微化石生物地层学研究表明，该复合记录的时间跨度从中新世气候适宜期的起始阶段，一直延伸至墨西拿盐度危机的初期。
