In the beginning, this chapter briefly summarizes the historical development of ideas regarding the causes of chemical variations in magmatic suites, from mediaeval times to the present. It stresses the importance of current revolution driven by improving analytical techniques, providing large amounts of increasingly precise major- and trace-element analyses, as well as data on a growing number of isotopic systems. Later, it provides an overview of available PC programs for interpretation of whole-rock geochemical data from igneous rocks. Finally it outlines the importance of open-source software and introduces the R language and the Geochemical Data Toolkit (
GCDkit
), written in R. Both are used extensively throughout this book (for their fundamentals, see Appendices A and B).
