通过分析鸭绿江口及邻近浅海表层沉积物的碎屑矿物特征,讨论了表层沉积物中主要碎屑矿物的沿程变化、指示性矿物、特征指数方面的差异及其示踪意义。研究结果表明:鸭绿江口与邻近浅海的沉积物可能来自于不同的物源区;西水道的沉积保留了较多的鸭绿江历史沉积的特点;中水道沉积与现代河流相近;辽东浅滩的沉积物质来源以河流为主,兼有来自浅海的物质。 By analyzing the characteristics of detrital minerals in the surface sediments of the Yalu River estuary and the adjacent shallow sea, the variation of major detrital minerals in the surface sediments, the differences of indicator minerals and characteristic indices and their tracing significance are discussed. The results show that the sediments of the Yalu River estuary and the adjacent shallow sea may come from different provenance areas; the sedimentation of the West Water Channel retains more features of the Yalu River historical sedimentation; the sedimentation of the Middle Channel is similar to that of the modern river; Mainly rivers, both from the shallow sea material.
