| 摘 要： | 根据对西藏念青唐古拉构造变形分析及地质年代测定资料，将该区构造变形划分为晚侏罗世到早白垩世的伸展拆离，形成区域性面理构造；晚白垩世到渐新世聚敛作用，形成斜向逆冲构造及雁列式褶皱；中新世以来的伸展、隆升，形成念青唐古拉剥离断层及羊八井地堑。

THICK SKINNED THRUST TECTONICS AND ITS SIGNIFICANCE TO EXPLORATION OF CONCEALED COALFIELD IN XINGLONG COALFIELD AND ADJACENT AREA, HEBEI PROVINCE |
| |
| Abstract: | The characteristics of plane distribution and shallowing upward in cross section of the main thrust zone in the southern area of Xinglong coalfield has been determined on the basis of detailed mapping. According to the principle of balanced cross section, the shortening volume induced by thrusting is estimated to be about 13 75km. The successful probability of exploration of concealed coalfield beneath the thrust zone is very limited depending on the geometrical and kinematical features of the thrust tectonics developed in this area. |
