我国海底热液活动研究的阶段性进展与展望

中国科学院海洋研究所
摘要:
海底热液活动调查研究是深海进入、深海探测和深海开发的切入点之一。近十年来,中国在西太平洋弧后盆地、东太平洋海隆、大西洋洋中脊和印度洋脊,发现了一批新的海底热液活动区,围绕着热液活动区的硫化物、流体、热液柱、生物等热液产物开展了调查研究,构建了海底热液地质学,提出了热液活动、冷泉及天然气水合物的同源异汇假说,出版了《海底热液地质学》、《现代海底热液硫化物成矿地质学》、《现代海底热液活动》、《东太平洋海隆热液地质》专著,获得了一批调查研究成果。未来,聚焦海底热液活动的深部过程及其资源环境效应关键问题,发展海底热液活动探测技术,拓展极地海底热液活动调查研究新领域,围绕烟囱体、热液柱、含金属沉积物、流体以及热液区生物等热液产物,开展深入、系统的调查研究工作,无疑将推动海底热液地质学取得新的进展。

Research progress and prospect of submarine hydrothermal activities in China

Abstract:
The investigation and study of submarine hydrothermal activity is one of the key assignments for deep-sea entry, deep-sea exploration and deep-sea development. In recent ten years, a number of new submarine hydrothermal fields have been discovered in the western Pacific back arc basin, the Eastern Pacific Rise, the Mid-Atlantic Ridge and the Indian Ridge by China scientists. A large number of investigations have been carried out on the hydrothermal products such as sulfide, vent fluid, hydrothermal plume and organism in the hydrothermal fields. The submarine hydrothermal geology has been constructed, and the hypothesis of same methane source and exhibit different methane sinks for submarine hydrothermal activity, cold-seep and gas hydrate have been elaborated. On the basis of above researches, China scientists have obtained a number of research achievements, including published the monographs "Submarine Hydrothermal Geology", "Modern Seafloor Hydrothermal Sulfide Metallogenic Geology", "Modern Seafloor Hydrothermal Activity", and "Submarine Hydrothermal Geology of the East Pacific Rise". In the future, it is important to continue focus on the subseafloor geologic process of hydrothermal activity and the key issues of its resource and environmental effects, develop the detection technology of submarine hydrothermal activity, expand the new field of investigation and research on polar submarine hydrothermal activity, and carry out systematic investigation and research on hydrothermal products such as chimney, hydrothermal plume, metalliferous sediment, vent fluids and hydrothermal organisms, which will undoubtedly promote the new development of study on submarine hydrothermal geology.
