黄河中游地表土壤的粒径和重矿物成分有一定的地区分布规律。在暴雨之后,洪水挟带大量地表冲刷物质进入河道。一部分泥沙淤积在沿河滩地上。在考证黄河1843年历史洪水时,就是利用该年洪水泥沙淤积物的颗粒组成、重矿物成分等特性,结合黄河中游暴雨洪水的发生规律论证了该年洪水是来源于陕北皇甫川、窟野河、无定河一带及泾河马连河、洛河

The grain size and heavy mineral composition of the surface soil in the middle reaches of the Yellow River have certain regional distribution rules. After the torrential rains, the floodwaters carry a large amount of surface scouring material into the river. Part of the sediment deposition in the beach along the river. In the study of the history of the Yellow River in 1843 floods, is the use of the flood sediment sediment particles, heavy minerals and other characteristics, combined with the occurrence of rainstorms in the middle reaches of the Yellow River demonstrated that floods that year were from northern Shaanxi Huangfuchuan, cave Wild River, Wudinghe area and the Jinghe Ma Lianhe, Luohe
