静北潜山地层岩性主要为变质陆源碎屑岩、混和岩、碳酸盐岩、蒸发岩及硅质岩等 ,与邻区的大红峪组、高于庄组、杨庄组、雾迷山组岩性特征极为相似 ;微古植物有 2 0属 33种 ,特征化石及化石组合特征可与邻区蓟县剖面的中元古界对比 ;潜山地层中的伊利石结晶度为 12 2～ 15 0 ,b0 值为 9 0 30～ 9 0 6 6 ,变质程度为浅变质绿片岩相 ,而邻近区域只有中元古界具有这样的特征 ;地球化学特征也与邻区中元古界的高于庄组、杨庄组、雾迷山组类似 ,而与古生界的差别极大。综上所述 ,静北潜山地层应与邻区中元古界的大红峪组、高于庄组、杨庄组和雾迷山组相当。
The lithology of Jingbei Beishan strata is mainly metamorphic terrigenous clastic rocks, mixed rocks, carbonate rocks, evaporites and cherts, which are closely related to the Dahongyu Formation, Gaoyuzhuang Formation, Yangzhuang Formation, The lithological characteristics of Shannxi Formation are very similar. There are 20 species and 33 species of microfossils in this area. The characteristics of fossils and fossils can be compared with that of Proterozoic in the Jixian section of the adjacent area. The crystallinity of illite in the buried hill is 12 2 ~ The value of b0 is 9 0 30 ~ 9 0 6 6, and the degree of metamorphism is the pale metamorphic greenstone facies, while only the Proterozoic in the adjacent area has such features. The geochemical characteristics are also similar to those of the Proterozoic in the adjacent area Yuzhuang group, Yangzhuang group, similar to the Wumishan Formation, and extremely different from the Paleozoic. In summary, the Jingbei Beishan formation should be similar to the Dahongyu Formation, Gaoyuzhuangzhuang Formation, Yangzhuang Formation and Wumishan Formation in the adjacent Proterozoic.
