现有为数不多的分析资料表明,海洋含金属沉积物比其它类型深海沉积物汞的含量高。考虑到含金属沉积物处在构造-岩浆活动区,这些资料也许可以被看成是海底火山喷气中大量的汞进入沉积堆积介质的证据。但是汞在含金属沉积物中的堆积也可能与其被铁和锰的氧化物吸附提取有关。这些
The few available analytical data show that marine metal-bearing sediments have higher levels of mercury than other types of deep-sea sediments. Given the presence of metal-bearing sediments in the tectono-magmatic activity zone, these data may be considered as evidence of large amounts of mercury entering the sedimentary accumulation medium in submarine volcanic jets. However, the accumulation of mercury in metal-bearing sediments may also be related to their adsorption by iron and manganese oxides. These ones
