Forward Modelling in R
This chapter contains three solved problems on forward modelling of the behaviour of isotopes using R (see Chap. 16 for principles). The exercises deal with plotting mixing hyperbolae for a single isotope system (in the Sr vs. 87Sr/86Sr and 1/Sr vs. 87Sr/86Sr coordinates) and an Sr–Nd isotope pair (in the 87Sr/86Sr vs. 143Nd/144Nd plot). The last exercise simulates the effects of AFC processes in the 1/Sr vs. 87Sr/86Sr space.
