| 摘 要： | 利用岩石薄片、扫描电镜、能谱和阴极发光等资料,对塔里木盆地巴楚-麦盖提地区石炭系小海子组混积型碳酸盐岩中石英的分布、产状和成岩作用进行了研究.根据粒度统计结果,与碳酸盐混积的陆源石英来源于海滩砂或沙丘砂.陆源石英与碳酸盐的混合是海平面上升期由沿岸流等事件作用产生.纵向上石英含量的变化与沉积环境和事件作用的不确定性有关....

| Abstract: | The distribution,occurrence and diagenesis of quartz in mixed clastic-carbonate rocks in Xiaohaizi Formation of Carboniferous system in Bachu-Makit Area of Tarim Basin were studied by using thin section observation,SEM,EDS and cathode-luminescence.Through average diameter statistics,it was considered that the terrigenous quartz was from beach or dune.The sedimentation event during sea level rising can result in the terrigenous quartz mixing with carbonate.The content of quartz in vertical direction was irre... |
