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 顏色反射率可以反映沉積物的物質(zhì)組成和礦物學(xué)信息,進(jìn)而反映沉積環(huán)境、沉積作用和物質(zhì)來源。
( 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 )提出了表土層元素富集因子和風(fēng)化剖面元素遷出因子,用于估算巖石風(fēng)化對水體及其沉積物、土壤的化學(xué)組成影響的程度。
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 結(jié)果表明:在黑色頁巖風(fēng)化過程中, cd 、 sb 、 zn 、 u等元素對殘積土壤組成影響較大, ree 、 y 、 cr 、 cu等元素對周圍水體及沉積物組成影響較大,而v 、 ni 、 mo 、 t1等元素對殘積土壤和周圍水體及沉積物組成影響都較大。
