测试了南极企鹅聚集区阿德雷岛湖泊沉积物 Sr、Ba、B、Ga的垂向含量变化 ,阿德雷岛湖泊沉积物元素平均含量为 :Sr为 10 6 9.36± 42 2 .10 mg/kg,Ba为 2 13.84± 39.48mg/kg,B为 6 .89± 3.79m g/kg,Ga为 16 .6 5±3.91mg/kg,阿德雷岛湖泊沉积物 Sr/Ba比值为 4.92± 1.5 3,B/Ga比值为 0 .43± 0 .2 6 ,Sr/Ba比值远大于 1.0 ,而B/Ga比值小于 3.3,这表明在特殊的生态环境下 Sr/Ba比值不能用来判别沉积物的沉积相 ,南极阿德雷岛湖泊沉积的 Sr/Ba比值异常是通过企鹅生物地球化学过程沉积改造而引起的 ,受到企鹅粪沉积影响
The vertical contents of sediments Sr, Ba, B and Ga in the lake of Adelie Island in Antarctic penguin agglomeration area were tested. The average contents of sediments in the lake of Adelaide were: Sr 10 6 9.36 ± 42 2 .10 mg / kg, Ba of 2 13.84 ± 39.48 mg / kg, B of 6.89 ± 3.79 mg / kg, Ga of 16.65 ± 3.91 mg / kg, and Arrrei Lake sediment Sr / Ba ratio of 4.92 ± 1.5 3, the ratio of B / Ga is 0.43 ± 0.226, the ratio of Sr / Ba is much larger than 1.0, and the ratio of B / Ga is less than 3.3, which indicates that the Sr / Ba ratio can not be used to distinguish sediments in special ecological environment Sedimentary facies, the Sr / Ba ratio anomalies in the Antarctic lake are caused by sedimentation and transformation of penguin biogeochemical processes and are affected by the sedimentation of penguins
