The rapid rise of atmospheric oxygen content in Paleoproterozoic (i.e., Great Oxidation Event) resulted in many dramatic changes in earth's surficial system, including the 2.3 similar to 2.06Ma positive delta C-13(carb) excursion, termed Lomagundi-Jatuli Event, which has been a focus of international geological and geochemical studies. The Lugezhuang Formation, lower portion of the Jingshan Group, is a high amphibolite to granulite facies metamorphic carbonate association. Herewith we report the results obtained from isotope and element geochemical study of 26 marble and 7 dolomitic quartzite samples from the Lugzhuang Formation at Shanhou village. The delta C-13(carb) values of the samples range from -0.8 parts per thousand to +3.4 parts per thousand (V-PDB), with an average of +1.4 parts per thousand. The delta C-13(carb) averages of marbles and dolomitic quartzites are +1.6 parts per thousand and +0.9 parts per thousand, respectively. The delta O-18(carb) values range from 9.3 parts per thousand to 20.2 parts per thousand (V-SMOW), with an average of 14.0 parts per thousand. The delta O-18(carb) and delta C-13(carb) values positively correlate, and 13 samples show Mn/Sr ratios of >6. This indicates that the delta C-13(carb) values of carbonates have been intensely modified by metamorphism, possibly causing a decrease of delta C-13(carb) values by 3 parts per thousand to 5 parts per thousand. Hence, the delta C-13(carb) values originally sedimentary carbonates are possibly up to +8.4 parts per thousand, showing positive delta C-13(carb) excursion characterizing the global Lomagundi-Jatuli Event.
