宝力高庙组是二连—贺根山造山带的重要组成部分,是认识二连—贺根山造山带弧沟体系的重要“窗口”。结合相关地质工作成果,对内蒙古阿巴嘎旗宝力高庙组一段沉积地质特征及构造属性进行了分析,结果表明:(1)宝力高庙组一段时代为晚石炭世至早二叠世;(2)宝力高庙组一段总体构成一向上变浅的沉积序列,下部为陆湖相沉积,上部为河流相沉积;(3)宝力高庙组一段砂岩骨架颗粒统计分析结果反映出其物源构造属性为岩浆弧。综合上述分析推测宝力高庙组一段的沉积构造环境为弧内盆地。
Baoligaomiao Formation is an important part of the Erlian-Hegen Mountain orogenic belt and is an important “window ” for understanding the arc system of the Erlian-Hengenshan Orogenic Belt. Based on the related geological work results, the sedimentary geologic features and tectonic attributes of Baoligaomiao Formation in Abaga Banner, Inner Mongolia were analyzed. The results show that: (1) Baoligaomiao Formation was a period from Late Carboniferous to Early Permian ; (2) the first member of Baoligongmiao Formation has an ever-shallow sedimentary sequence, the lower part of which is sedimentary facies of the lacustrine facies and the upper part of the sedimentary facies; (3) The statistical analysis of the sandstone particles in the first member of Baolgaozao Formation reflects Its provenance is magmatic arc. Based on the above analysis, it is speculated that the sedimentary tectonic environment in the first section of Baolgaozao Formation is intra-arc basin.
