摘要
草沟堡区位于河北省蔚县南山腹地,与蔚县煤田同处于Ⅳ级构造单元——蔚县复向斜内,该区广泛分布下花园组之上覆地层九龙山组、张家口组,并表现为向斜构造,基底为奥陶系和寒武系灰岩。近期在草沟堡区外围李家堡发现了含煤地层中—下侏罗统下花园组露头,推测在草沟堡向斜中部也有下花园组赋存,是有希望的找煤区。
The Caogoupu area is located in southern mountainous hinterland of Yuxian, Hebei Province, together with the Yuxian coalfield, it stand in the same Ⅳ category structural unit - the Yuxian synclinorium. In the area, Xiahuayuan Formation superjacent strata Jiulongshan Formation and Zhangjiakou Formation are widely spread and forming a syncline, while the basement is Ordovician and Cambrian limestone. Recently in Lijiapu, peripheral Caogoupu area have found outcrops of coal-bearing Mid-Lower Jurassic Xiahuayuan Formation, it can be supposed that the formation also exists in the middle part of Caogoupu syncline, so that is also a prospecting area for coal looking.
