sediment composition meaning in English

沉积成分
沉积物成分

Sediment composition and mineralogical constituents can exert primary and local influence on color reflectance , so sedimentary environment , sedimentary process and material source can be inferred by sediment color spectral
颜色反射率可以反映沉积物的物质组成和矿物学信息，进而反映沉积环境、沉积作用和物质来源。
( 4 ) we defined ssee factor ( surficial soil element enrichment factor ) and wpem factor ( weathering profile element mobility factor ) , and applied them to evaluate the degree of effects of black shales weathering on soil , water bodies and their sediments composition
( 4 )提出了表土层元素富集因子和风化剖面元素迁出因子，用于估算岩石风化对水体及其沉积物、土壤的化学组成影响的程度。
The results are as follows : trace elements such as cd , sb , zn and u can change residual soil composition deeply , elements such as ree , y , cr and cu can change water bodies and their sediments composition deeply , while elements such as v , ni , mo and tl can change residual soil , water bodies and their sediments composition deeply during black shales weathering
结果表明：在黑色页岩风化过程中， cd 、 sb 、 zn 、 u等元素对残积土壤组成影响较大， ree 、 y 、 cr 、 cu等元素对周围水体及沉积物组成影响较大，而v 、 ni 、 mo 、 t1等元素对残积土壤和周围水体及沉积物组成影响都较大。
