| 摘 要： | 伊敏五牧场区存在着从褐煤到贫煤完整的变质系列,其主要煤变质类型为接触变质.在本区煤系地层底部有一酸性侵入岩体,该侵入岩体是引起本区煤变质的直接热源,它提供了褐煤向烟煤转化的热动力.本区出现的隐爆角砾岩也是受热不均匀或热叠加造成煤类复杂多变的原因.区内构造十分发育,构造条件是煤变质的又一主要因素.研究该区煤变质规律对伊敏煤田及海拉尔褐煤盆地烟煤预测具有指导作用.

| Abstract: | There is a complete metamorphic series of coal from lignite to meager coal in Wumuchang area, Yimin, the main metamorphism type is contact metamorphism of coal. In the bottom of coal measures is an acidic intrusive body, it is direct heat source of metamorphism, and provided the conversion of lignite to bituminous coal with thermodynamic power. Again, the present of cryptoexplosive breccia in the area is also a causation of heterogeneous and stacking heating of coal during meta- morphic process and made the coal rank complicated. Because of well-developed structures in the area, the structural condition is another main factor of coal metamorphism. To sum up, the study of coal metamorphism has guiding significance in bituminous coal prediction in Yimin coalfield and Hailar lignite basin. |
