西太平洋海底热液活动与资源联合科考取得重要突破

Quick Look

清华大学、中国地质调查局青岛海洋地质研究所、上海交通大学等单位组成的科考团队在西太平洋新锁定一处大型高温活动热液区,初步证实具备大规模多金属硫化物资源潜力。科考队于8月10日从深圳起航,历时18天实施7次探测器下潜作业,发现热液喷口端元流体最高温度超315℃,伴生金最高含量达15.4ppm,伴生银最高含量达1271ppm,平均含量水平显著优于陆地矿床。

近日,由清华大学、中国地质调查局青岛海洋地质研究所、上海交通大学等单位开展的西太平洋海底热液活动与资源联合科考航次取得重要突破。科考团队依托自主研制的设备在西太平洋新锁定一处大型高温活动热液区,初步证实具备大规模多金属硫化物资源潜力。

本次科考任务,科考队搭乘“向阳红10”号科考船,于今年8月10日从深圳起航,在历时18天的科考航程中,在位于我国专属经济区的西太平洋弧后盆地内实施了7次探测器下潜作业。

据介绍,在开展本次科考之前,该科研团队人员已经对这片海域开展了十多次前期探测,找到了数十处高温热液喷口,这些喷口位于水下约700到1500米的深度,喷口端元流体最高温度超315℃,热液活动十分活跃。本航次在之前调查基础上,通过精细调查和原位取样又在盆地内精准锁定了一处全新且规模巨大的海底热液活动矿区,所伴生的热液硫化物矿体由3个大型圆锥状矿体结构构成。经船载实验室初步检测分析,该矿体主要由黄铜矿、黄铁矿、闪锌矿等重要经济矿物组成,对部分样品的初步分析显示,矿石中伴生金的最高含量达15.4ppm,伴生银的最高含量达1271ppm,其平均含量水平显著优于陆地矿床。

Research from the Chinese Academy of Sciences: The strength of the ancient geomagnetic field 260 million years ago was about 51% of modern times

Through research on the layered gabbro in the Baima mining area of Panzhihua, a research team from the Tibetan Plateau Institute of the Chinese Academy of Sciences found that the strength of the ancient geomagnetic field 260 million years ago was about 51% of modern times. The findings do not support the hypothesis that weakening of the geomagnetic field caused biological extinction in the Late Permian.

Wu Derong analyzes the development of tropical disturbances in the South China Sea: Local rainfall is forecast to affect eastern and northeastern Taiwan over the weekend

Wu Derong, an adjunct associate professor at the Department of Atmospheric Science at National Central University, cited European and American weather models and pointed out that a tropical disturbance in the South China Sea is brewing and moving generally towards Vietnam. It is expected to bring localized short-lived showers in the northeastern and eastern half of Taiwan over the weekend. There is also a chance of rainfall in the mountainous areas in the afternoon. It will still be hot during the day and slightly cool in the morning and evening.
