鄂尔多斯盆地西南部晚三叠世构造背景来自碎屑锆石的约束

The Late Triassic tectonic setting in the southwestern Ordos basin is constrained by detrital zircons

盆地陆缘碎屑沉积物既是盆地沉积和构造演化的直接证据和重要标志,同时反映了该区域地质背景的信息。认为陆源碎屑沉积物是在区域构造背景控制下的物源区与沉积盆地有机结合配置的产物,也是揭示这种关系及其构造环境的重要标志。

Clastic sediments of the basin is not only a direct evidence of the sedimentary and tectonic evolution of the basin,but also a reflection of the information of the regional geological background information.Genetic relationship between basin types ofterrigenous clastic sediments,that is a product of the configuration of the organic combination of provenance in under the control ofregional tectonic setting and sedimentary basins,it is also an important symbol of this relationship and its tectonic environment.
