摘要

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20属种

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122～150

b0值为9.00～9.066

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.

Abstract

Jinbei buried hill consists mainly metamorphic terrigenous clastic rock

diamictite

carbonatite

evaporite and silicite. Paleo-microphytes of the study area include 20 genera and 33 kinds

the characteristic fossils and the fossil assemblages could be correlated to that of Middle Proterozoic in Jixian County nearby.Illite crystallinity of the buried hill is 122～150

bo-value is 9.030～9.066

showing low metamorphic greenschist facies. In short

the strata of the buried hill show similarity in lithology

lithofacies

fossils

metamorphic grade and geochemistry with those of Middle Proterozoic Dahongyu

Gaoyuzhuang

Yangzhuang

Wumishan Formations of the neighbouring areas but differ greatly from those of the Paleozoic. So it is suggested that the strata should correspond to the above mentioned formations.
