中新世期间有众多的事件。诚如深海钻探岩芯的沉积分析所获得的古海洋学资料证明的那样,中新世是构造运动很活跃的时期,导致大陆处于接近现今的位置,并形成环南极海流,它决定了晚第三纪太平洋水流循环的基本特征。南极东部已经结冰,而在中新世末—上新世初,南极西部也开始结冰,影响到水的同位素组分的形成,并明显地改变了世界大洋的水准面。沉积过程的多次间断和与碳酸盐补偿面的多次抬升有关的碳酸盐溶解旋回,都证明底层
During the Miocene there were numerous events. As evidenced by paleoceanographic data obtained from the sedimentary analysis of deep-sea drilling cores, the Miocene was a period of tectonic activity that led to the mainland being in a position close to today and forming a circular Antarctic current which determines The Basic Features of the Triassic Pacific Ocean Circulation. At the end of the Miocene-Pliocene, the Antarctic ice also began to freeze, affecting the formation of isotopes of water and significantly changing the world oceanic level. Multiple discontinuities in the deposition process and carbonate dissolution cycles associated with multiple uplift of the carbonate compensation surface all demonstrate that the bottom layer
