大洋钻探对海底热液活动研究的贡献

CONTRIBUTION OF OCEAN DRILLING TO THE STUDY OF SEAFLOOR HYDROTHERMAL ACTIVITY

大洋钻探为海底热液活动研究提供了大量数据资料和样品。在此基础上,通过研究流体—沉积物/岩石相互作用,热、物质通量和流体流动,分析构造对海底热液活动的控制作用,使人们对海底热液循环有所了解,并对深部热液成因石油的特征,海底热液沉积物的空间结构和物质组成,以及深部生物与海底热液活动的关系有了一些认识。未来通过实施IODP,海底热液活动研究将会取得更多新的成果。

Abundant data and samples have been recovered by ocean drilling for studying the seafloor hydrothermal activity. On the basis of these data and samples, we have understood the seafloor hydrothermal circulation by studying the fluidsediment/rock interaction, the heat and mass flux, the fluid flow, and the tectonics in control of seafloor hydrothermal activity. And we have got some knowledge about the characteristics of seafloor hydrothermalorigin petroleum, the architecture and constitute of seafloor hydrothermal products, and the relationship between the deep biosphere and the seafloor hydrothermal activity by analyzing these data and samples from the ocean drilling. In the future, more achievements of studying seafloor hydrothermal activity will be got by carrying out the Integrated Ocean Drilling Program.
