| 摘 要： | 青阳花岗闪长岩体及其围岩中均发育压扁变形构造，形成环状向斜、线理、边缘片麻理、热收缩张节理的构造组合。变质变形作用、结合岩石学特征的分析结果显示，岩体是以刺穿式底辟作用就位于早古生代地层中的。

| Abstract: | Flaser structure is developed in the granodiorite, and its wallrocks,forming the tectonic pat-tern of annular syncline, lineation, marginal gneissosity and contracted tension joints. Study of its deforma-tion-metamorphism and petrological characteristics indicates that the inclusion emplaced into the early-palaeozoic strata through diapirism. |
