Dear researchers;

## Can anybody give me geochemical background concentration values of the elements in the Earth’s crust (crustal average).

###  Also, I need a values of elements  trace in :

"Clarke values" n chemical composition of the upper continental crust ( UCC) ( Taylor and McLennan, 1995).

Geochemical background concentration of the heavy metal (crustal average) (Taylor and McLennan, 1985)

I need for these Some papers :

[1] K. K. Turekian and K. H. Wedepohl, “Distribution of the elements in some major units of the earth’s crust,” Geological Society of America Bulletin, vol. 72, no. 2, pp. 175–192, 1961.

[2] D. R. Lide, CRC Handbook of Chemistry and Physics,Geophysics,Astronomy, and Acoustics, Abundance of Elements in the Earth’s Crust and in the Sea, section 14, CRC Press, Boca Raton, Fla,USA, 2005.

Thank you
