以往调查表明:在水系沉积物的细粒部分,锡含量大幅度减少。这种减少反映了细粒锡石不可能混入到沉积物中去,而是分配在流域内的水系悬浮物中去。尽管悬浮质与被河流搬运的全部物质有关,但在化探中尚未广泛利用分析悬浮沉积物来寻找金属(包
Previous surveys have shown that there is a significant reduction in tin content in the fine-grained portion of sediments. This decrease reflects the fact that fine-grained cassiterite can not be incorporated into sediments but rather to be dispersed in aqueous suspensions in the basin. Although the suspended matter is related to all the material transported by the river, it has not been widely used in geochemical exploration to analyze suspended sediments for metals
