鞍山群

鞍本地区鞍山群变质矿物及变质作用

Metamorphic Minerals and Metamorphism of Anshan Group in Anshan-Benxi Area Liaoning

华北地台北缘东段多期褶皱及构造置换对鞍山群铁矿床的控制作用

Control of polyphase folds and structural transposition

辽东半岛南部太古宙鞍山群的原岩建造

Original formation of the metamorphic rocks of Archean Anshan Group in the south of Liaodong Peninsula

中鞍山群黑云母变质温度为550&620℃，变质压力在5×10~8Pa左右；

The biotite metamorphic temperature of the middle Anshan Group is 556-620 ℃, the pressure is less than 5 × l0 ~ 8Pa ;

多期褶皱和构造置换是华北地台北缘太古宙鞍山群岩石中的主要变形特征，也是对太古宙鞍山群铁矿的形态、规模、产状和分布规律的主要控制因素。

Polyphase folds and the structural transposition are main deformation characteristics fo the Archaean Anshan Group in the northern margin of North China platform , and also are important factors to the shape , scope , occurrence and distribution pattern of Anshan Group iron deposits .
