【摘要】 <正> 关于南海北部第四纪海平面变化问题,过去研究甚少。近年来,由于沿海和近海陆架石油勘探事业,以及海岸带和海涂资源综合调查等工作的推动,在南海北部地区开展大量的海洋地质与地貌调查研究工作中,发现了许多能够确定年代和当时海面位置的地貌、沉积与生物标志。这为探讨这一地区不同时期的海平面变化提供了较充分的依据。本文根据已有研究资料,对我国南海北部晚更新世以来的海平面变化进行探讨。更多还原

【Abstract】 Based on abundant data, the eustatic fluctuation in the north of South China Sea which has appeared since the Late Pleistocene is discussed with the evidences indicating ancient sea level and the features showing fluctuation of sea level. The author considers that: (1)The lowest sea level in Wurm-glaciation set at the elevation from-150m. to-160m. (2)After Wurm-glaciation, the sea level rose rapidly. It arrived at-110m. in 12, 000B.P. and at -60m. in 11, 000B.P. Some stops occured in the period. (3)The highest sea level appeared in Holecene. Then the sea level fell down undulately and attain the present position.更多还原
