| 中文摘要: |
| 河北省变质核杂岩形成于中-新生代,围绕华北拗陷盆地呈环带状分布在太行山、燕山地区。分为穹状和长垣状两种。同美国科迪勒拉式变质核杂岩相比,在主拆离断层内缺失巨厚的韧性剪切带。其形成的动力机制包括岩浆底辟、区域大陆伸展和地幔(亚)柱上隆作用。 |
| 英文摘要: |
| The metamorphic core complexes in Hebei were formed during Mesosoic-Cenosoic Period occuring as belts in Taihang, Yanshan mountain areas etc, in the surroundings of the North China Depression. They are formed by magma diapirism, continental extension and mantle plume. However the huge ductile shear zones in Cordilleran metamorphic core complex are absent here. |
