| Abstract: | he studing areas are located in Zhuozi and Helan Mountains region. Its carboniferous strataare mainly composed of elastic rocks, including a little of carbonate. The stratigraphic seguence is dividedinto the Jiangyuan Formation (C). Yanghugou Formation (C) and Taiyuan Formation (C3).Thesedimentary factes are a typical delta depositinal system. The upper delta plain is the best coal - bearingenvironment. |
