| 摘 要： | 玉溪盆地位于滇中普渡河断裂带南端，新第三纪含煤地层主要由冲积扇—湖泊、沼泽和河流—湖泊成因层序构成。南北向盆缘断裂的构造样式及其走滑作用方式的改变，提供了局部扭张或扭压构造环境，导致盆地的形成、发展和构造反转。依据详细的沉积和构造分析，提出了盆地形成及构造反转的地球动力学模式。

| Abstract: | Yuxi Basin is located at the south part of the Puduhe fault zone. The upper Tertiary coal bearing strata are composed of allurival fan lacustrine swamp and flurial lacustrine sequences. The variations in structural settings and the styles of strike slip of the boundary faults of the basin(the Puduhe fault), led to the formation, development and tectonic reverse of Yuxi Basin under a transtentional or transpressional tectonic enviroment. Based on detailed sedimentary and structural analyses, a geodynamic model for the basin formation and its tectonic reverse is built in the present study. |
