Lower Continental Crust

Description

A data set containing the composition of the Lower Continental Crust as recommended by Rudnick and Gao (2014). This article is a revision of the previous work Rudnick and Gao (2003).

Usage

CC_Lower__Rudnick_Gao__2014

Format

A data frame with 1 row and 84 element concentrations. These elements are:
SiO2, TiO2, Al2O3, FeO*, MnO, MgO, CaO, Na2O, K2O, P2O5, Li, Be, B, N, F, S, Cl, Sc, V, Cr, Co, Ni, Cu, Zn, Ga, Ge, As, Se, Br, Rb, Sr, Y, Zr, Nb, Mo, Ru, Pd, Ag, Cd, In, Sn, Sb, 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, Nb/Ta, Zr/Hf, Th/U, K/U, La/Yb, Rb/Cs, K/Rb, La/Ta, Mg#, Eu/Eu*, Heat production

Details

In this work the concentrations of the major elements (as oxides) are given in wt%. The concentrations of all other elements are given in ug/g (ppm) or ng/g (ppb). For the sake of unity the values given in ppb where converted to ppm using ppm= ppb/1000.
The listed values for the major elements (oxides) are in wt% and all other elements are given in ppm. Heat production is given in mW/m^3.
