单矿物及地球化学特征浅析——以内蒙古鄂温克旗头道桥地区糜棱岩为例

On the Single Mineral and Geochemistry Features:Taking the Mylonite in Toudaoqiao Area, Ewenki of Inner Mongolia for Cases

头道桥糜棱岩是以塑性变形为主的韧性剪切带,形成了糜棱岩、碎裂岩系列,该糜棱岩带中糜棱岩的原岩均为花岗岩,该韧性剪切带中的糜棱岩化花岗岩、花岗质初糜棱岩以及花岗质糜棱岩的单矿物化学特征和岩石地球化学特征与岩石变形强度增大和退变质作用增强有着密切的关联,他们都表现出了一定的规律性。

Mylonite in Toudaoqiao is the toughness shear zone mainly with plastic deformation, which formed mylonite and cataclasite, the original rock of mylonite in the mylonite zone is granite, the chemical features of single mineral and the earth of the mylonite granite, mylonite and granitic mylonite have close relationship with the increase of the deformation and metamorphism of the rock, they are showing a certain amount of regularity.
