| 摘 要： | 政和地区变质岩石在晋宁期遭受了３期构造变形作用（Ｄ）。以这３期构造变形作用为相对时间标志，讨论了变质砂泥质岩石中各种不同产状、不同种类变质矿物的生长期，确定了基质主要加粗期为Ｄ２－Ｄ３变形期间的静态期。进而将晋宁期变质作用划分为早期、主期和晚期３个变质阶段，变质作用的主期为Ｄ２变形期和Ｄ２－Ｄ３变形期间静态期。

| Abstract: | Three singes of structural deformation durinS Jinning Period can be recognized from the metamorphic rocks in Zhenghe area,Northern Fujian. The different occurenas of metumorphhosed sandy argrillite and the different growth Period of metumorphic minerals have herein been studied by tubing the three stages of structural deformation as a relative time mark. It is couctuded that the major growth Period of marix in the metamorphic rocks occures for the septic stages between the second and third singes of structural deformation. However, the metamorphism during Jinning Period can be divided the early stage, the main stase and late sarge. The main stage of metumorphism took place in the deformation stage (D2) and in the static stage between the second and third Singes of structural deformation. |
