| 摘 要： | 发生于中生代-新生代之间的事件是地质历史上一次重大灾变和异常事件,因此白垩系-古近系之间的界线(K/T界线)就成为全球最重要的地质界线之一.通过对塔里木盆地西北缘乌恰地区库孜贡苏河剖面海相上白垩统-古新统地层的岩性和沉积环境变化以及地球化学特征研究,重点利用沉积物色度、有机碳含量、碳酸钙和碳、氧稳定同位素的明显异常变化...

| Abstract: | The catastrophe and extinctions occurred in late Cretaceous is one of the most severe events during the geo-logical history,a thin clay boundary worldwide deposited on the earth during this period was calledK-T boundary. The nerth western Tarim Basin is an ideal experimental field preserving continuous Late Cretaceous-Paleogene marine stratum and excellent outcrops in China.Previous researchers have done a lot of work and made a series of important achievements,however,the research and discussion on the pal... |
