RELATIONSHIPS BETWEEN THE JINGSHAN GROUP AND THE FENZISHAN GROUP IN THE JIAOBEI AREA

摘要: 本文对分布于胶北地区的下元古界荆山群、粉子山群从岩石组合、微量元素、同位素年龄数据以及区域资料诸方面进行了对比。对二者在变质作用、含矿性、构造样式及底部岩石组合等方面存在的差异进行了分析，提出二者是同时异相之观点。

Abstract: This paper makes a correlation between the Lower Proterozoic Jingshan Group and Fenzis-han in the Jiaobei area in respect to rock associations ,trace elements,isotopic age data and re-gional geology,and analyzes their differences in metamorphism,ore potentialities,tectonic sylesand basal rock associations.Aview that both were formed at the same time but at the differentplaces.
