Division Features of Coal-bearing Tectonic Units in North China

摘要

Based on the new round of national potential evaluation on coal resources, and reference to the latest achievements about regional geological and energy basins, this article analyzed the main features of North China coalfield structure. According to the main features of North China coalfield structure and the distribution of North China coal series, the boundary of North China coal-bearing tectonic region and the division of North China coal-bearing tectonic units were identified. North China coalfield tectonic region can be divided into 5 coal-bearing tectonic sub-regions and 22 coal-bearing tectonic zones. The basic characteristics of the tectonic structure and its influence upon coal series distribution in each coal-bearing tectonic zone were systemically discussed.
