#' Upper Continental Crust
#'
#' A data set containing the composition of the _Upper Continental Crust_ as
#' recommended by \insertCite{Rudnick2014;textual}{georefdatar}. This article is
#' a revision of the previous work \insertCite{Rudnick2003;textual}{georefdatar}.
#'
#' 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`.\cr
#' 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.
#'
#' @format A data frame with 1 row and `r ncol(CC_Upper__Rudnick_Gao__2014)` element concentrations. These elements are:\cr
