井陉北部煤田构造方向为北北西——南南东,至东西方向之构造,则变动较小者居多。其对於煤田地质构造有决定性之构造有下列诸项。 1.井陉大断层——为造成并陉槽形地层(Graben)之主要原因,断层西壁为奥陶纪石灰岩,北至马头山有馒头页岩露头,更北之小寨,罗钵一带并见五台系片岩及震旦纪石英岩露头。断层走向近於南北。 The coalfield in the northern part of Jingjing has a tectonic orientation of North, West, South-South, and East-West directions, with the smallest changes occurring. The coal geological structure for the decisive structure of the following items. 1. Jingxing Large Fault - Mainly responsible for the formation of the Graben formation, the western wall of the fault is Ordovician limestone, there are steamed bun shale outcrops to the north of Ma Tau Shan, northern Xiaozhai and Luo Bowe See also the Wutai schist and Sinian quartzite outcrop.
