    摘要
  • 摘要: 海水中的氦同位素能对海底热液活动进行有效示踪。本文对在西南印度洋49°~56°E洋脊段采集的5条CTD拖曳剖面共14件深水样品进行了氦氖同位素分析。通过分析水体中存在的氦同位素异常，探讨调查区热液异常的特征和热液羽状流的分布。分析表明，5条CTD剖面均存在δ3 He异常，其中CTD7-2（位置：37.927°S、49.412°E，水深2 140 m，离底高度100 m）的δ3 He值最大，达到49.2%。根据δ3 He分布特征，认为调查区内存在至少6处热液羽状流，其中37.927°S、49.412°E以西数千米范围内可能存在海底热液喷口。
    Abstract: The helium isotope anomaly in the seawater is a good indicator of the hydrothermal activity in the seafloor. During DY115-21 cruise Leg 7,five CTD Toyo profiles were deployed between 49°E and 56°E on the Southwest Indian Ridge and 14 seawater samples were collected for helium and neon isotope analysis. In this paper,we examine the helium isotope anomalies in the water column and discuss the distribution of the hydrothermal plumes in the investigated area. Our results show that all of the five CTD profiles exhibit distinct δ3 He anomalies. Sample CTD7-2 which was sampled at 37.927°S,49.412°E in the water depth of 2 140 m (100 m above the seafloor) exhibited the largest δ3 He anomaly of 49.2%. According to the distribution pattern of δ3 He,it is suggested that there may existed at least 6 hydrothermal plumes in the investigated area,and one active hydrothermal venting site probably lies within a few kilometers west of 37.927°S,49.412°E.
