    The Petrogenesis of the Permian Podong Ultramafic Intrusion in the Tarim Craton, Western China: Constraints from C-He-Ne-Ar Isotopes by Mingjie Zhang, Pengyu Feng, Tong Li, Liwu Li, Juerong Fu, Peng Wang, Yuekun Wang, Zhongping Li, Xiaodong Wang

    Published 2019-01-01
    “…The results show that olivine, pyroxene, and plagioclase minerals in the Podong intrusion have variable δ13C of CO2 (-24.5‰ to -3.2‰). The CH4, C2H6, C3H8, and C4H10 hydrocarbon gases show normal or partial reversal distribution patterns of carbon isotope with carbon number and light δ13C1 value of CH4, indicating the hydrocarbon gases of biogenic origin. …”
