| 摘 要： | 汝箕沟矿区无烟煤产于侏罗纪地层中,在宁夏地区中生代煤中变质程度最高。本文简述了汝箕沟矿区变质煤系的基本特征,首次论证了该区早白垩世晚期玄武岩的发育是引起煤层变质的最直接和主要原因,并简述了该玄武岩的特征、发育构造背景及其区域意义。

| Abstract: | Rujigou coalfield is famous for the output of anthracite coal produced from the Jurassic strata,where the metamorphism degree is the highest in the Mesozoic coal of Ningxia area.Here it is simply discussed that the characteristic of metamorphic coal in Rujigou coalfield and firstly confirm that the Late Mesozoic basalt developed in Gugutai area is the main and direct cause of coal metamorphism in Rujigou area.And it is also specified that the characteristic of the basalt,producing background and regional significance. |
