利用J .B .Maynard ,R .Volloni和W .R .Dickinson等人建立的砂岩碎屑模型 ,对塔里木盆地柯坪、巴楚断隆志留 -泥盆系砂岩碎屑特征进行研究 ,分析砂岩的物源区类型及构造意义 ,并探讨柯坪、巴楚断隆历史上的亲缘关系。通过研究认为柯坪、巴楚断隆砂岩碎屑参数及碎屑模型十分相似或相近 ,说明两者在古生代时为同一构造单元或具相同的构造背景 ,具有良好的亲缘关系 ,现今的构造差异则为后期构造运动的结果。柯坪、巴楚断隆碎屑参数及碎屑模型的局部差异 ,总体反映为巴楚断隆的石英含量高 ,C/Q比值高 ,这些差异主要是在相同物源区类型条件下 ,由于表生改造作用、沉积环境及成岩作用差异造成的。
Based on the model of sandstone detritus established by J.B. Maynard, R.Volloni and W.Dickinson et al., The detrital characteristics of the Silurian-Devonian sandstone in Keping and Bachu, Tarim Basin, are studied, and the characteristics of sandstone The type of source area and its tectonic significance, and to explore the kinship in the history of Keping and Bachu. According to the research, it is considered that the clastic parameters and clastic models of Keping and Bachu fault-broken sandstones are very similar or similar, indicating that they were the same tectonic unit or the same tectonic setting in the Paleozoic with good genetic relationship and the present structural differences It is the result of later tectonic movement. The local differences of detrital parameters and detrital models in the areas of Keping and Bachu are generally reflected by the high quartz content and high C / Q ratio in the Bachu break-off. These differences are mainly due to the fact that in the same type of source area, Superficial remodeling, sedimentary environment and diagenesis.
