| 摘 要： | 莺歌海盆地是发育在古红河断裂带之上的新生代盆地，晚第三纪的构造运动触发了盆地中热流体自超压封存箱向外大规模突破，使热流体及泥质的活动具有规律性成群成带的特征。本次实验基于相似理论，在对盆地的演化史及区域构造应力场充分分析的基础上，进行了晚第三纪盆地构造应力场的三维泥料模拟，证实了红河断裂右旋走滑派生的拉分效应控制了莺歌海盆地晚第三纪的构造活动，而晚第三纪的构造活动又是雁列式断裂展布及底辟体分布的主导因素。

| Abstract: | The Tertiary Yinggehai basin was formed on the Pale-Red River fault zone, trending NW. Tectonism in the Late Tertiary triggered massive hot fluid explosion from overpressure compartment, which resulted in the regular distribution of mud and fluid activities. Based on comparability theory and systematic analysis of the evolution and regional stress field of the basin, the stress field in the Late Tertiary was simulated. It was confirmed that the structure style of the basin was controlled by the pull-apart effect of the dextral strike-slip Red River fault and the tectonic activities in the Late Tertiary led to the en echelon faults and diapirs. |
