摘　　要：王玉净等 1998年撰写的“广西钦州小董 -板城上古生代硅质岩相地层” ,新建了上泥盆统“石梯组” ,该岩石地层单位与谢家荣、王植 1937年在广西西湾创建的石梯系 (后更名石梯组 )重名。根据地层命名优先权 ,西湾侏罗系石梯组应予沿用 ,钦州板城上泥盆统“石梯组”应予废弃。钦州板城含有上泥盆统放射虫、牙形类的硅质岩与上覆含有下石炭统放射虫、牙形类的硅质岩不同 ,后者含有锰矿和赤铁矿 ,颜色较深 ,根据岩石地层学组的含义 ,将前者重新命名为桂南组。The upper Devonian'Shiti Formation' was built by WANG Yu jing and his colleges in 1988 in the paper entitled'Xiaodong Bancheng plate Palaeozoic silicalite strata in Qinzhou,Guangxi Zhuang Autonomous Region'. Because this rock stratigraphic unit was named after the Jurassic 'Shiti System (Shiti Formation)' built by XIE Jia rong and WANG Zhi in 1937, it is suggested that the upper Devonian'Shiti Formation'should be renamed as 'Guinan Formation' which contains Late Devonian Radiolaria and Conodont ,different from the Early Carboniferous silicalite coexisting with rhodochrosite and hematite.
