Pyrolite

Description

A data set containing the recommended chemical composition of the of the Silicate Earth-”Pyrolite” as given by McDonough and Sun (1995)

Usage

Pyrolite__McDonough_Sun__1995

Format

A data frame with 1 row and 76 element concentrations in ppm:
Li, Be, B, C, N, F, Na, Mg, Al, Si, P, S, Cl, K, Ca, Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ga, Ge, As, Se, Br, Rb, Sr, Y, Zr, Nb, Mo, Ru, Rh, Pd, Ag, Cd, In, Sn, Sb, Te, I, Cs, Ba, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Hf, Ta, W, Re, Os, Ir, Pt, Au, Hg, Tl, Pb, Bi, Th, U

In the article the concentrations of most of the major elements are given in wt% and the concentrations of Nb and following are given in ppb.
For the sake of clarity these values where converted to ppm: So all values given here are in ppm.
This conversion was done using:

• ⁠ppm= wt% * 10000⁠

• ppm= ppb / 1000
