| 摘 要： | 甘肃金塔及其所在的河西地区均是煤炭资源严重缺乏的地区。区内尽管煤点出露较多，但在深部煤层常常缺失或尖灭，针对这一现象，本文从构造单元划分人手，运用板块构造学的分析方法对本区的构造活动史进行了简明的阐述，断陷盆地成为本区赋煤的主要构造。

| Abstract: | Jinta County,Gansu Province and the whole Hexi Corridor the Jinta County seated are seriously lack of coal resources. Although there are numerous coal outcrops in the region,but usually are hiatus or thinning out in depths.Point to this phenomenon,the paper proceeded with structural element division,took the advantage of plate tectonic analytical method to outline the tectonic history, thus held an opinion that the faulted basin is main coal hosting structural form in the region. |
