| 摘 要： | 在辽宁西部建昌县查家店-养马甸子-回流水一带,发育有长度11.5 km、宽约1 km的韧性剪切带.通过多次实地调查,根据宏观的SC组构和镜下的旋转应变构造分析,判断养马甸子韧性剪切带为右行剪切机制,剪切位移1780m.该韧性剪切带发育在新太古代麻计沟单元花岗岩中,而东侧多处可见中元古代长城纪高于庄期堆积物呈角度不整合覆...

| Abstract: | An 11.5 km long and 1 km wide ductile shear zone is developed in Zhajiadian-Yangmadianzi-Huiliushui area of Jianchang County, Western Liaoning Province. Based on field surveys, with petrofabfic study and microscopic rotational strain analysis, the Yangmadianzi ductile shear zone is decided to be right-lateral sheafing mechanism, with 1780 m sheafing displacement. The ductile shear zone occurs in the granite of Neoarchean Majigou unit, which is covered unconformably by the accumulation of Mesoproterozoic Changcheng system, suggesting that the forming period of the ductile shear zone should be from late Neoarehean to Mesoproterozoie. |
