简介：Lomagundi-Jatuli事件(LJE)是保存13C在在世界范围的Paleoproterozoic碳酸盐的+5和+16之间的carb价值。然而，这些旅行的持续时间，振幅和模式仍然保持糟糕抑制了。在北方中国Craton的2.14-1.83GaHutuo组是一>10km厚火山--沉积顺序，包括>5km在在上被扔的厚保存得很好的碳酸盐--对亚tidal环境潮汐。碳酸盐的152件最不改变的样品的公司同位素、元素的分析揭示了三阶段的13C进化。它以只积极的13Ccarb(+1.3到+3.4)在Dashiling和Qingshicun形成在~上演2.1Ga碳酸盐，从积极价值由转变列在后面到震荡在~的积极、否定的价值3000mWenshan，Hebiancun，Jianancun，和Daguandong形成的厚碳酸盐，并且与只否定的13C保存在的carb价值>500mHuaiyincun和Beidaxing形成的厚dolostones。看来许多LJE，特别地那些极其积极的13Ccarb信号，没在Hutuo碳酸盐被记录。只积极的13Ccarb价值(+1.3到+3.4)多半在更低的形成保存了对应于LJE的目的，而随后二个阶段反映LJE和Shunga-Francevillian事件(SFE)的发作的余殃。现在的数据点到碳上的氧的增加的影响从Doucun骑车到Dongye亚群并且证明在北方中国Craton的LJE的结束与在Fennoscandia和南非的那些是将近同时的。
