摘要 根据凤县地区草滩沟群的岩石组合特征、沉积示顶构造将其自下而上划分为红花铺组、张家庄组和龙王沟组.从所产生物化石组合面貌、沉积叠履关系分析,红花铺组时代为早奥陶世,张家庄组和龙王沟组应归入晚奥陶世. According to characteristics of rock association, the Caotangou Group in the Fengxian area can be divided, from top to bottom. into the Honghuapu Group, Zhangjiazhuang Group and Longwanggou Group The occurrences of fossil assemblage and analysis of the sedimentary overstepped relationship ascribed the Honghuapu Group to the Early Ordovician period,the Zhangjiazhuang Group and the Longwanggou Group to the Late Ordovician period.
