摘要
通过对鹤岗煤田区域地层、区域构造、岩浆活动规律的分析研究,阐述了鹤岗煤田煤变质作用以区域变质作用为主,局部出现接触变质作用。在走向上煤的变质程度由南向北逐渐增高,在倾向上煤层随赋存深度的增大变质程度逐渐增高。
Through analysis of Hegang coalfield regional stratigraphy, structure and magmatic activity patterns, the paper expounded that the coal metamorphism in the area is mainly regional metamorphism, locally some contact metamorphism. Degree of metamorphism steps up along the strike from south to north, whereas steps up along the dip in company with depth.
