| 摘 要： | 在层序格架内研究川东北元坝地区三叠系飞仙关组碳酸盐岩台地演化及其影响因素。元坝地区三叠系飞仙关组划分为2个三级层序、4个体系域。元坝地区飞仙关组碳酸盐岩台地在不同时期、不同区域受到构造抬升和高位溢流的影响。在层序SQ1海侵期，元坝北部受到构造抬升的影响，外缓坡外侧沉积厚度反而大于外缓坡内侧厚度。从层序SQ1海侵期持续到高位初期的构造抬升减小了台地中缓坡与外缓坡的差异，促使台地规模迅速向北扩大。在层序SQ1高位期，元坝东部高位溢流现象显著。高位期台地可容纳空间减小，限制了台地的垂向加积潜力，沉积物向外缓坡方向侧向前积，出现高位溢流。鲕滩主要发育在高位溢流不同阶段所形成的中缓坡和缓坡斜坡内。

| 关 键 词： | 缓坡 高位溢流 层序 元坝地区 四川盆地 |
