Chondrite

Description

A data set containing the composition of the CI chondrite as given by McDonough and Sun (1995)

Usage

CI__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

Details

In the original work 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
