| 摘 要： | 可保煤盆地位于滇中小江断裂带中段，新第三纪含煤地层主要由冲积扇一湖泊、沼泽成因层序构成。南北向主干断裂左行走滑活动和侧列接续样式提供了局部扭张或扭压构造环境，导致基底断块的相对运动，从而控制了拉分盆地的构造演化。根据详细的沉积－构造分析，本文提出了煤盆地形成和形变的地球动力模式。

| Abstract: | The Kebao coal basin is located at the middle segment of the Xiaojiang fault belt inthe central part of Yunnan Province.The coal-bearing strata are made up of alluvial fan-lacus-trine-swamp genetic sequences.The sinistral strike-slip activities and overstepping pattern ofthe principal fault trending N-S have led to the relative motions of basement faulted blocks un-der a transtentional or transpressional tectonic environment.Based on detailed sedimentary-structural analyses,the paper establishes the geodynamic models for the coal basin formationand its deformation. |
