Upper Continental Crust

Description

A data set containing the composition of the Upper Continental Crust as given by Taylor and McLennan (1995)

Usage

CC_Upper__Taylor_McLennan__1995

Format

A data frame with 1 row and 64 element concentrations in ppm. These elements are:
Li, Be, B, Na, Mg, Al, Si, P, K, Ca, Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ga, Ge, As, Se, Rb, Sr, Y, Zr, Nb, Mo, Pd, Ag, Cd, In, Sn, Sb, Cs, Ba, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Hf, Ta, W, Re, Os, Ir, Au, Tl, Pb, Bi, Th, U

Details

In this work the concentrations of most elements are given in ppm and some concentrations are given in wt% or ppb.
For the sake of unity the values given in either wt% or ppb where converted to ppm. So all listed values are in ppm.
This conversion was done using:

• ⁠ppm= wt% * 10000⁠

• ppm= ppb / 1000
