    海底冷泉标志与主要冷泉区的分布和比较

    THE INDICATORS OF SEABED COLD SEEP AND COMPARISON AMONG MAIN DISTRIBUTION AREAS

    • 摘要: 海底冷泉从发现到现在已经近40年,主要发生在大陆边缘及边缘海盆地。海底冷泉的地球物理探测、地球化学研究、地质现象等提供了冷泉的寻找标志。在研究海底冷泉的过程中,一般从地球物理探测、海洋原位探测、生物地球化学和生物标志化合物等角度去研究冷泉的形成过程及环境,这些研究巩固并扩展了冷泉的寻找标志。对于沉积物中的元素,采用主成分因子分析法判断物质来源和分布,为分析冷泉的产物时提供了一个宏观背景。重点比较了我国近海的7个冷泉区域,并从冷泉碳酸盐岩和生物群落两方面对全球3种代表性的地质背景下的冷泉区域做了比较。通过比较指出了冷泉研究存在的问题和未来的研究方向。

       

      Abstract: It is almost 40 years since the first seabed cold seep was discovered. Cold seeps mainly occur on the edge of continental margins and marginal-sea basins. The geophysical, geochemical and geological characteristics of submarine cold seeps are of great significance to the understanding of cold seeps. Geophysical and biogeochemical indicators, biomarker compounds and in-situ monitoring are important to the study of the forming mechanism and environments of cold seeps. As far as the elements of sediments are concerned, major component may contribute to the discrimination of source materials and provide a background for study of cold seeps. A total of 7 cold seep areas from China and 3 areas abroad are selected for comparison of authigenic carbonates and their biocenosis. Discussion is made on future tasks in cold seep studies.
