Based on the study of rock textures and structures, and stable isotopes of dolomite and S isotope of barite interlayers within the cap dolomite outcropped in the Miaohe area in the Three Gorge, it is testified that the stable isotopes show a strong negative excursion, and the isotopes of sulfur show a significant positive excursion, which is similar to the reported data of authigenic barites formed in a modern seafloor gas hydrate environment. Therefore, it can be concluded that the cap dolomite was most likely formed in a special environment under which a huge gas hydrate dissociated with the breakup of "Snow Earth" in later Neoproterozoic.

通过对湖北三峡庙河地区出露的&盖帽&白云岩的野外地质构造、碳－氧稳定同位素和重晶石夹层的硫稳定同位素特征的研究，发现除了明显的碳稳定同位素的负偏移之外，重晶石的硫同位素值表现出明显的正偏移，其数值可与现代海底甲烷喷气孔附近的自生重晶石矿物的同位素组成相对比，进而认为&盖帽&白云岩的成因是末元古代&雪球&事件之后天然气水合物的释放与全球环境突变背景下的沉积产物。

But the models also suggest that the scheme could go too far: Adding excess sulfur could increase ice in Antarctica,"overcompensating" for warming, says Rasch, which could affect ecosystems and the global ocean-atmosphere system in a myriad of ways that scientists haven't studied.

拉什说：&但是，模型实验显示计划的最终效果可能事与愿违，南极冰层会因为大气层中注入过多的硫磺而增厚，使全球的生态系统和海洋大气系统受到影响，产生这些影响的方式是多种多样的，有可能完全超出科学家们的研究范围，从而造成比全球变暖更严重的后果，让我们得不偿失。&
