| 摘 要： | 对吉中地区石炭系下统余富屯岩组进行了描述和分析,展示了该套地层的沉积学特征,确定了研究区展布的余富屯岩组为浅海相沉积环境,同时伴有火山喷发活动。通过同位素测年手段,揭示了该套地层取样点位处的火山岩形成年龄,从而确定了余富屯岩组的地质年代。

| Abstract: | The Yufutun Formation of Lower Carboniferous in Jizhong area is described and analyzed,showing the sedimentary characteristics of the strata,indicating that the Yufutun Formation distributed in the study area is a shallow marine sedimentary environment accompanied by volcanic eruption.By means of isotope dating,the formation age of volcanic rocks at the sampling sites of this set of strata is revealed,thus the geological age of Yufutun Formation is determined. |
