| 摘 要： | 本文通过对原鱼洞子群的系统研究，将其解作为以太古界表壳岩为主体的鱼洞子岩群和太古代TTG高级变质片麻岩套，认为本区太古代结晶基底为花岗-绿岩-高级变质表壳岩地体，指出本区太古代已存在类刚性板块构造。

| Abstract: | Based on the original Yudongzi group systematically, it is suggested that the originalYudongzi group would be divided into Yudongzi rock group and Archeozoic TTG gneiss suitwith high-grade rnetamorphism. It is suggested that the Archeozoic crystal basement be com-posed of the granite-greenstone-high-grade metamorphic surface rock, The like-rigid platetectonice shouId exist in the area. |
