摘要
通过内蒙古地区红水泉农场附近早石炭世红水泉组砂岩阴极发光和砂岩骨架分析,对其岩石学特征及物源进行研究。结果显示,内蒙古额尔古纳地区早石炭世红水泉组砂岩岩性为石英砂岩和含砾石英砂岩;母岩类型主要为中-高级变质岩,少量深成岩;形成于深成岩或火山岩中,少部分石英形成于低级(区域)变质岩中;物源可能来源于稳定的克拉通内部深部地层的隆升。
Through the nearby Red springs farm in Inner Mongolia area in the Early Carboniferous Hongshuiquan formation sandstone cathodoluminescence and sandstone skeleton analysis, studied the petrological characteristics and provenance. The results show, Inner Mongolia Eergu' Na area in the Early Carboniferous Hongshuiquan formation lithologic sandstone quartz sandstone and quartz sand with gravel; parent rock type is mainly in a high--grade metamorphic rocks, formed in the plutonic or volcano plutonic rocks; rock, a small part of quartz formed in lower (regional) metamorphic rocks, source may be derived from the stability of the through the deep strata uplift.
