摘要
盆地性质厘定是沉积盆地分析的基本任务之一,也是目前国际地学界研究的热点。近年来的研究表明碎屑化学成分比其骨架颗粒成分更能反映盆地和物源区的构造性质。作者利用侏罗系碎屑岩化学成分(Fe2O3+MgO、TiO2、Fe2O3/K2O、SiO2/Al2O3及K2O/Na2O)厘定新疆焉耆中生代盆地为断陷盆地。

Wu FuQiang Engineer Petroleum Geology Sedimentary Institute Chengdu College of Technology Chengdu 610059 China Abstract An identification of basin properties is one of basic tasks for a sedimentary basin analysis. At present it becomes one of key points of studies in international geologic circle. The studies of recent yesars show that clastic chemical constituents could reflect structural properties of a basin or a source material area better than its matrix components. This paper makes an identification of Mesozoic basin in Yanqi as a faulted basin according to its Jurassic clastic chemical constituentsFe2O3+MgO TiO2 Fe2O3/K2O SiO2/Al2O3 and K2O/Na2O.
