摘要
Carboniferous volcanics rocks are widely distributed in the eastern area of Bageda Mountain with the lower level of research. According to 1:50 000 region geological surveys, the authors are individed Carboniferous rock into three formations. In this paper, the volcanic rock geology and petrology, major element, REE, trace elements geochemistry characteristics are studied. The results show that the Lower Carboniferous Qijiaojing formation and the Upper Carboniferous Liushugou formation are bimodal volcanic construction and the major of tholeiite. The Upper Carboniferous Qijiagou formation is volcanic rock-clastic-carbonate construction with small scope. All volcanic rocks within research area are series of lime-alkali tholeiite.
