晚古生代,华北可划分为三个巨型纬向构造带,即阴山纬向构造带、秦岭纬向构造带及位于其间的华北纬向沉降带。阴山纬向构造带主体大致分布在包头—呼和浩特—张家口—沈阳一带;秦岭纬向构造带的主体部份大致分布在永寿—灵宝—南阳—固始一带,其北支大体分布在潼关—宜阳—密县一带。山西地区即大体位于华北巨型纬向沉降带的中段。晚古生代以来,阴山、秦岭纬向构造带和华北纬向沉降带的演变,对山西地区的古地理轮廓、沉积环境、岩相分异、聚煤作用的演化具有决定性的控制作用。但在山西地区内
Late Paleozoic, North China can be divided into three giant zonal tectonic belts, namely, Yinshan zonal tectonic belt, Qinling zonal tectonic belt and located in the north latitudinal subsidence zone. The main body of the Yinshan zonal structural belt is generally distributed in Baotou-Hohhot-Zhangjiakou-Shenyang area; the main part of the Qinling zonal structural belt is generally distributed in the area of Yongshou-Lingbao-Nanyang-Gushi area, with its northern branch generally distributed in Tongguan- Yang - dense county area. Shanxi is generally located in the middle of the huge zonal subsidence zone in North China. Since Late Palaeozoic, the evolution of Yinshan, Qinling zonal structural belt and latitudinal subsidence zone in North China have a decisive controlling effect on the paleogeography, sedimentary environment, lithofacies differentiation and the evolution of coal accumulation in Shanxi Province. But in Shanxi area
