摘要
华南板块北缘江西萍乡武功山地区发育的穹窿状变形变质体属岩浆核杂岩,其结构特征和成因机制,与经典的变质核杂岩有相似之处,但其核部是花岗岩,它主要是花岗岩浆强力底辟侵位引起地壳局部隆升和伸展滑覆。在这些伸展滑覆体系之下,掩盖了大片的含煤岩系地层,因此,该区是寻找隐伏煤田的理想靶区。
Domal deformational-metamorphic body which developed in Wugongshan region of Pingxiang City, Jiangxi Province in the north margin of Huanan Plate belongs to magmatic core complexes. It is similar to classical metamorphic core complexes in texture characteristics and genetic mechanism , except for the core which is made up of granite. The strong diapir emplacement of granite led to uplifting and gliding nappe in local crust. A large area of coal-bearing series was covered under this extensional gliding nappe series. As a result, this region is regarded as an ideal target for finding potential coalfield.
