| 摘 要： | 胶北隆起区变质基底岩性较复杂,从中分离出正变质侵入岩,并按单元-超单元理论对其进行了谱系单位划分,其中古元古代吕梁期侵位的一套花岗闪长岩-二长花岗岩类侵入岩划为双顶超单元,根据其穿插关系、矿物成分及结构构造特征等进一步划分出5个单元。双顶超单元其侵位受构造控制,分布范围较广,同源岩浆演化特征明显。

| Abstract: | Rock property of magnetic baserock is very complicted in Jiaobei uplift area, and positive mag-matic intrusive rocks are departed from it. Lineage unit classification is carried out according to unit-superunit theory. Among them, granodiorite-monzonitic granite type intrusive rocks in Paleoproterozoic Lvliang period is classified into Shuangding superunit. According to its nterluding relation, mineral compositions and structural characteristics, it is divided into 5 units furthurly. Intrusion of Shuangding superunit is controlled by structure with wide distribution scope, and conmagmatic evolution characteristics is evident. |
