Rumble, geochemist Andrey Bekker of the University of Manitoba in Winnipeg, Canada, and several other colleagues hit upon a clue to the sulfur's origins in ancient rocks from Western Australia.

有关硫的来源，朗布尔和加拿大曼尼托巴大学的地球化学家安德雷·贝克以及其他几个同事，从来自澳大利亚西部的古代岩石中偶然发现了线索。

The sulfur is" critically important," says geochemist Douglas Rumble of the Carnegie Institution of Washington in Washington, D.C.It concentrates nickel into a form that can be mined commercially.

华盛顿哥伦比亚特区华盛顿卡内基研究所的地球化学家道格拉斯·朗布尔说，其中的硫是“非常重要的”。是硫将镍集中起来，形成硫化镍，从而使镍成为一种可以用商业规模进行开采的金属。

The discovery solves a mystery that has dogged researchers for decades, says geochemist Edward Ripley of Indiana University, Bloomington, who was not affiliated with the study.

印第安纳大学布卢明顿分校的地球化学家爱德华·里普利称，该发现解开了一个困惑研究人员几十年的谜团。里普利没有参与这项研究。
