| 摘 要： | 本文应用沉积学手段对贵州平塘甘寨剖面中二叠统茅口组进行详细的沉积特征和层序地层的研究。研究结果显示,茅口组主要的岩石类型有亮晶-微晶生屑灰岩、生物灰岩、微晶灰岩、亮晶内碎屑灰岩、硅质岩、瘤状灰岩和含燧石灰岩等,茅口组生物种类有介形虫、腹足、腕足、三叶虫、藻类、棘屑、蜒、珊瑚、海百合茎等。岩石学特征和生物组合指示,平塘甘寨地区中二叠统茅口组为开阔碳酸盐台地沉积环境,包括台内滩和滩间两个亚相。茅口组可划分出3个Ⅲ级层序PSQ1、PSQ2和PSQ3,均由海侵体系域（TST）与高水位体系域（HST）两部分组成。层序发育受到了海平面升降变化控制,层序之间的界面P2q/PSQ1、PSQ1/PSQ2、PSQ2/PSQ3皆为岩性-岩相转换面,层序界面P3l/PSQ3在茅口末期受到东吴运动的影响,为构造不整合面。
