Radiocarbon datings of Upper Quaternary bottom sediments from the Mediterranean Sea

Bottom sediment samples were collected in the Central Mediterranean, Southern Adriatic, Tyrrhenian, Algerian-Provencal, and Alboran basins of the Mediterranean Sea. Fifty-six datings were done for 12 sediment cores. The lowest sedimentation rates during Holocene were found on the abyssal plain of the Algerian-Provencal basin (2.4-4.0 cm/ky). In the Southern Adriatic, Tyrrhenian, and Alboran basins sedimentation rates were somewhat higher (6-12 cm/ky). On slopes of the Southern Adriatic and Tyrrhenian basins during Late Würm glaciation rates of \"normal\" sedimentation were within the range 11.8-26.8 cm/ky.本研究采集了地中海海域中地中海盆地、南亚得里亚海盆地、第勒尼安海（Tyrrhenian）、阿尔及尔-普罗旺斯（Algerian-Provencal）以及阿尔沃兰（Alboran）等盆地的海底沉积物样品。针对12根沉积物岩芯共开展了56次年代测年工作。全新世（Holocene）期间的最低沉积速率出现在阿尔及尔-普罗旺斯盆地的深海平原，取值范围为2.4~4.0 cm/ky。南亚得里亚海盆地、第勒尼安海盆地与阿尔沃兰盆地的沉积速率相对更高，介于6~12 cm/ky之间。在南亚得里亚海盆地与第勒尼安海盆地的斜坡区域，玉木冰期晚期（Late Würm glaciation）的‘常规’沉积速率介于11.8~26.8 cm/ky之间。
