| 摘 要： | 从复杂的构造变形中甄别出岩浆岩的塑性流动变形,与韧性和脆-韧性变形区别,力争还原长乐—泉州沿海一带地质构造的真实面目,并探讨了该带的活动时间和构造属性。另外还对该带长期争论的澳角群进行了初步的分解,锆石SHRIMP测年数据也反映了平潭南务里一带变质岩的复杂性。

| Abstract: | The paper make s a discrimination from the difference between the plastic-flow deformation and the ductile and brittle-ductility deformation in the complicated tectonic deformation.The author tries his best to open out the primary features of geological structures along the sea-board area of Changle and Quangzhou cities and the activity time and structure attribute of the suveyes area are also under a discussion in the paper.Otherwise,it makes a simply study for the stratum unit Aojiao Group which is disputed for a long period of time.The dating data of a zircon show the complexity of metamorphic rocks in the Nanwuli area of Pingtan County. |
