瑞典东南部造山期后花岗岩体的东侧有眼球状片麻岩产出,它们一般与围岩协调一致地褶皱,但在几个地段,似乎转变为横切(围岩)的造山期后花岗岩.Finspang地区的眼球状片麻岩反映出该区可能是造山期后花岗岩的顶盖或向下变尖的倒钩构造,这种构造与Ramberg(1967)的离心模型实验中的一种相类似.几个要素表明,这类花岗岩是以凝结岩浆的形式侵位的,假想的演变模型与气球构造模式具有某些共同的特性(Ramsay,1981),然而,把它理解为由于岩浆扩张,使其外壳环绕成一个简单的气球状构造,不如认为是由于岩浆膨胀使其顶盖发生变形,造成向下变尖,形成一个弯曲的倒钩构造更为合理.如果假设的这种关系能够成立,那么就可以认为,在瑞典东南部发生的广泛的变质作用和变形作用,是由于Sm?land花岗岩侵入的边界影响造成的.
Eruptive gneiss output on the eastern side of the granitic massif in the southeastern part of the country after orogeny, generally folds in synchronicity with the surrounding rock, but appears to have been transformed into transgressive (orogenic) post-orogenic granite The orbicular gneisses in Finspang reflect that the area may be the cap or downwardly pointed barb formation of granite after orogeny, a structure similar to that of a centrifuge model experiment by Ramberg (1967) Several elements indicate that such granites are emplaced in the form of condensed magmas, and that the hypothetical evolution model has some properties in common with the balloon tectonic patterns (Ramsay 1981). However, it is understood that due to the magma expansion Its shell is surrounded by a simple balloon-shaped structure, it is better to think that due to the magma expansion of its roof deformation, resulting in a downward spiral, forming a curved barb structure more reasonable if this assumption can be established, Then one can argue that the extensive metamorphism and deformation that occurred in the southeastern part of Sweden were caused by the boundary effect of Sm? Land granite intrusion.
