| 摘 要： | 平邑盆地是蒙山断裂多期次活动的产物，盆地内沉积了厚约1700多米的新生代古近纪官庄群杂色-红色碎屑岩建造。将官庄群沉积建造、剖面类型，结合含膏岩系的沉积特点，可以划分为3个不同级别的沉积韵律，它们分别反映出含膏岩系在时间和空间上的变化趋势。蒙山断裂及盆地内次级断裂的阶段性活动，使盆地表现为升降运动，下降时成矿物质聚集、保存，相对稳定期是膏岩形成的有利期。

| Abstract: | Pingyi basin is the product of multi - phase activities of Mengshan fault. The thickness of varicolored - red fragementals in Cenezoic Paleogene Guanzhuang group is 1700m. According to sedimentary foundation, profile types and sedimentary characteristics of gypsum - bearing strata, 3 degree of sedimentary rules can be divided, which respectively reflects variation trend of gypsum - bearing rocks in time and space. The initial activities of Mengshan fault and sub -fault made the basins show as elevation and subsidence, and ore -forming materials were formed and reserved when the was subsidence＆ A relatively stable period was the favorable period for ore -forming. |
