青藏高原的隆起与海洋锶同位素组成的演化

TIBET PLATEAU UPLIFT AND THE EVOLUTION OF MARINE STRONTIUM ISOTOPIC COMPOSITION

近年来，随着构造隆升驱动气候变化假说的提出，青藏高原的隆起受到越来越多的关注，并将之与大陆化学风化速率及海洋锶同位素的演化紧密联系。围绕青藏高原的隆升及其环境与气候效应，对海洋锶同位素组成的演化特征及其影响因素的较为全面而详细的论述表明：将青藏高原的隆升与全球气候变化、大陆化学风化速率及海洋锶同位素组成的演化相联系，也许是解决目前关于海洋锶同位素组成的演化及其物源问题的重要手段，根据海洋锶同位素的演化历史来研究全球气候变化规律及青藏高原的构造演化历史将是本研究领域的重点。

In the past few years, following the hypothesis of tectonically driven climate change, the uplift of Tibetan plateau receives increasing interest and is tightly connected with the rate of continental chemical weathering and the evolution of marine strontium isotope. This paper thoroughly and minutely discusses the influences of Tibet plateau uplift and the changes in the global environment and climate on marine Sr isotopic evolution and the possible factors influencing the evolution. It is an important approach to solve the problem of the evolution and sources of marine strontium isotope by combining the uplift of Tibetan plateau, the global climate change and the rate of continental chemical weathering. Research work in this field should be focused on the rules of global climate change and the tectonic evolution of Tibet plateau on the basis of the evolutionary history of marine strontium isotope.
