The team has shown that the Omani peridotite absorbs tens of thousands of tonnes of carbon dioxide a year, far more than anyone had thought.

该小组已经证明，阿曼的橄榄岩每年能吸收数以万吨的二氧化碳，这大大地超过了人们的想象。

They estimate this would allow the Omani outcrop, which extends down some 5km, alone to absorb some 4 billion tonnes of carbon dioxide a year, which is a substantial part of the annual 30 billion or so tonnes of the gas that humans send into the atmosphere, mostly by burning fossil fuels.

他们估计这将使阿曼这绵延五公里的露出地面的岩层，仅其一年就能吸收40亿吨二氧化碳，这相当于人类每年向大气中排放的300亿吨气体的很大一部分，这些气体主要由于人们燃烧化石能源产生的。
