摘　　要：在东北吉林地区,多数煤田资源赋存区火成岩发育,煤层不同程度受到火成岩侵蚀,受火成岩侵蚀部位在地震剖面上出现非沉积地层异常反应的地震相,通过对地震成相特征的充分研究和分析,就可有效地确定其产状和空间分布范围。In Jilin region,northeast China,most igneous rocks develop in the host coal rocks,coal seam were eroded by igneous rocks in different degree,in the seismic section,the eroded parts of igneous rocks show nondepositional seismic facies.Through the research and analysis of seismic facies characteristics,we can availably determine mode of occurrence and space distributive scope.

关 键 词：地震剖面 火成岩侵蚀区 空间分布范围 地震相
