摘要
应用聚煤盆地分析理论与方法,对黑宝山—木耳气盆地形成的地质环境和聚煤特征进行了分析研究。总结了半地堑式断陷盆地的构造格架、充填序列、沉积相的展布及煤层的分布、变化等规律,对于缺煤的黑龙江西部地区开展煤田勘查工作具有一定的指导意义。
The forming geological environments and the characters of accumulating coal in the Heibaoshan-Muerqi Basin are studied in this paper by means of the theories and methods oi accumulating coal basin analysis. And the authors summarized the rules of structure framework, filling sequences, the distribution of sedimentary facies, the distribution and changes of the coal-seams in the half-graben faultbasin, which can be a significant instruction for the exploration of coal fields in coal-absent western region of Heilongjiang.
