摘    要:鞍子山超单元由4个单元组成,各单元不同程度地发育岩浆侵位变形构造。侵位变形构造主要由叶理构造组成,闪长质包体,钾长石斑晶总体按优选方位定向,三者产状一致,平行接触带分布。从早期单元至晚期单元,随着岩浆侵位叶理构造变形强度减弱,闪长质包体数量减少,压扁变形程度降低,钾长石斑晶从明显按优选方位定向到杂乱分布。根据上述特征,将该超单元浆侵位变形、中等侵位变形、弱侵位变形及基本无侵位变形4个带。

关 键 词:辽宁庄河 鞍子山超单元 叶理构造 闪长质包体 岩浆侵位变形构造 晚侏罗世

Abstract:The Anzishan super-unit consists of four units,and magmatic emplacement deformational struc-tures are developed to different degrees in these units.The main structure is foliation,and dioritic inclu-sions and K-feldspar phenocrysts generally display preferred orientation.The three have a consistent attitude and are distributed parallelly to the contact zone.From the early-formed units to late-formed unit,with weakening deformation intensity of magmatic emplacement foliation structure,the number of dioritic inclu-sions is reduced,the degree of flattening deformation decreases and the oriented K-feldspar phenocrysts are distributed at random.According to the above-mentioned features,the magmatic emplacement deforma-tional structures of this super-unit is classified into strong emplacement deformation,moderate emplacement deformation,weak emplacement deformation and essentially no emplacement deformation zones.
Keywords:Anzishan super-unit  foliation structure  dioritic inclusion  magmatic emplacement deforma-tional structure  Late Jurassic  Zhuanghe  Liaoning
