【摘要】 南海珊瑚礁（尤其是西沙珊瑚礁）记录了青藏高原隆升、古季风、南海板块构造运动、火山喷发作用等方面的信息，是独特的古环境记录类型。本文着重探讨了上新世以来青藏高原隆升与西沙珊瑚礁海水锶同位素演化的关系，并建议大洋钻探计划在西沙珊瑚礁上钻探，系统识别和提取珊瑚礁中高分辨率的古环境记录。如能实现在西沙珊瑚礁设立大洋钻探计划航次，就可望为揭示青藏高原隆升、南海构造演化以及全球环境变迁的机理做出突破性的贡献。更多还原

【Abstract】 The coral reefs of the South China Sea, especially Xisha Islands, which contain a lot of information on the uplift history of the Tibetan Plateau, the tectonism.volcanic activity and palaeoenvironmental changes of the South China Sea, are a special kind of palaeoenvironmental record. Strontium isotope compositions in Xichen-1 well (16°27′IN, 111° 42′E )differ from the oceans, detailedly recorded the uplift of the Tibetan Plateau. A research endeavor combining the Tibetan Plateau investigations with the Ocean Drilling Program (ODP) in Xisha Islands will be most promisting in breaking through to reveal the mechanism behind the regional and global environmental changes. ODP’S drilling in the coral reefs is of great scientific significance for China and the world.更多还原
