摘要	The Lomagundi-Jatuli Event (LJE) is one of the largest and earliest positive carbon isotope excursions preserving delta C-13(carb) values between +5 and +16 parts per thousand in Paleoproterozoic carbonates worldwide. However, the duration, amplitude and patterns of these excursions remain poorly constrained. The 2.14-1.83 Ga Hutuo Group in the North China Craton is a >10 km thick volcano-sedimentary sequence, including >5 km thick well-preserved carbonates that were deposited in supra-tidal to sub-tidal environments. C-O isotopic and elemental analyses of 152 least altered samples of the carbonates revealed a three-stage delta C-13 evolution. It began with an exclusively positive delta 13C(carb) (+1.3 to + 3.4%o) stage in the similar to 2.1 Ga carbonate in the Dashiling and Qingshicun Formations, followed by a transition from positive values to oscillating positive and negative values in similar to 3 000 m thick carbonates of the Wenshan, Hebiancun, Jianancun, and Daguandong Formations, and end with exclusively negative delta 13C(carb) values preserved in >500 m thick dolostones of the Huaiyincun and Beidaxing Formations. It appears that much of the LJE, particularly those extremely positive delta C-13(carb) signals, was not recorded in the Hutuo carbonates. The exclusively positive delta 13C(carb) values (+1.3 to + 3.4%o) preserved in the lower formations likely correspond to the end of the LJE, whereas the subsequent two stages reflect the aftermath of the LJE and the onset of Shunga-Francevillian event (SFE). The present data point to an increased influence of oxygen on the carbon cycle from the Doucun to the Dongye Subgroups and demonstrate that the termination of the LJE in the North China Craton is nearly simultaneous with those in Fennoscandia and South Africa.
