Armed with this information and further analyses, Rumble, lead author Bekker, and colleagues propose the following scenario today in Science . Early in Earth's history, volcanic eruptions spewed massive amounts of sulfur dioxide into the atmosphere, where UV sunlight broke down the gas and created the odd sulfur isotope ratios. The sulfur descended with the rain and accumulated into sedimentary beds on the sea floor. Once there, superheated water from geothermal vents at various locations on the sea floor cooked the sulfur into sulfide. Finally, nickel-bearing magma welled up from Earth's mantle, combining with the sulfide to form nickel sulfide and encasing the compound inside volcanic rock called komatiite.

凭借这份资料和进一步的分析，朗布尔、研究论文的第一作者贝克及同事们今天在《科学》杂志上提出了如下的推测：在地球早期的历史上，火山爆发将大量的二氧化硫气体喷射到空中，太阳的紫外线将其分解，产生了奇特的硫同位素比值，这种硫随雨降下，积存于海底沉积层中；一旦到达海底，海底各处的地热出口所产生的温度过高的水把硫加热成硫化物；最终含有镍的岩浆从地幔中涌出，跟硫化物结合形成硫化镍，并将硫化镍包裹在一种叫做"科马提岩"的火山岩中。
