| 摘 要： | 区内存在５种等时性地层界面，据此将含煤岩系划分为６个成因单元，１０个亚单元。沉积环境经历了５个演化阶段，其中扇三角洲废弃阶段为最有利的聚煤时期。聚煤的有利部位位于废弃的扇三角洲体之上。

| Abstract: | here are five types of isochronous stratigraphic interfaces in Qixinghe exploration area,Sanjiang Basin. By Them the coal-bearing sequence is divided into six genetic stratigraphic unites and further into ten subunites. The depositional environment had involved five evolutional stages. Among them the fan-delta abandonment stage was the period most favoured to coal accumulation,and the best place for coal accumulation is on the abandoned fan-delta body. |
