太原东山含煤地层中腕足动物与氧碳同位素组成

通过对太原东山晚古生代含煤地层中腕足动物壳体的δ13C、δ18O值研究,揭示了腕足动物δ13C值和Z(相对古盐度)值的关系,δ13C值和Z值作为环境参数与相应腕足动物群落定性解释的生存介质条件相吻合,从而大大提高了腕足动物群落分析的重要性。进一步研究大区域内腕足动物群落生态,对聚煤盆地演化史的分析有重要的价值。 

RESEARCH ON BRACHIOPODS AND THEIR CARBON AND OXYGEN STABLE ISOTOPIC COMPOSITIONS FROM COAL-BEARING STRATA IN EAST HILL OF TAIYUAN

By the analysis and study of δ13C and δ18O values attained from the brachiopod fossils of Late Paleozoic coal bearing strata in East hill of Taiyuan,the relationship between δ13C value of brachiopod and Z value （relative paleosalinity） is revealed.The δ13C and Z values,as the environment parameters,are conformed with the existing condition of medium which is interpreted qualitatively by the corresponding brachiopod community,thus,the importance of brachiopod community analysis is increased greatly.The further ecological research on the brachiopod community regionally is of very important for the analysis of coal accumulating basin history.
