| 摘 要： | 赣西武功山地区发育的穹窿状变形变质体的组成结构和成因机制与经典的变质核杂岩有相似之处，它们由内核和外壳组成，并具三层式结构特征。但其内核主要为花岗岩，核内和核外的地层几乎同时代，并无“古老变质核”，它的形成机制主要是岩浆底辟强力侵住引起地壳局部隆升和伸展滑覆。本文将赣西武功山地区的穹窿状变形变质体改称为“武功山岩浆核杂岩”。

Discussion of the Structure Problem in Wugongshan Region in Western Jiangxi Province |
| |
| Abstract: | The genetic mechanism and its texture of domal deformational-metamorphic body is similar to classical metamorphic core complex in Wugongshan area. It is made up of inner core and outer crust which has three layer structure, but its inner core consists dominantly of granite, the strata in the core and out of the core are almost the same age which has no ancient metamorphic core. The genetic mechanism of the domal deformational-metamorphic body is mainly uplift and extensional gliding nappe in partly crust by diapiric strong emplacement of magma. Therefore, it is renamed Wugongshan magmatic core complex. |
