The Nankou Group can be divided in to four second-order sequences according to their fabric features of facies succession:The first second-order sequence of Nankou group （S5） consistent with the first member of Gaoyuzhuan Formation （or the Guandi subformation）, it’s lithologic character is variational: the lower part is a set of quartz sandstone, the thickness is 13 meters; the upper are mainly intertidal zone or supratidal zone deposits, which include stromatolitic dolomite with terrestrial clastics or argillaceous dolomite with dolomitic sandstone or dolomitic siltstone interbeded.
与大红峪组为平行不整合接触。 根据沉积组构特征,可划分为四个二级层序:第一个二级层序S5对应高于庄组一段(官地亚组),岩性特征为:底部为一套1～3米后的石英砂岩,向上为潮间带至潮上带含陆屑的叠层石白云岩、泥质白云岩,夹白云质砂岩、白云质粉砂岩。
