Introduction,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

Data Manipulation and Simple Calculationslems in igneous geochemistry. We shall follow the basic procedure from loading the data into the system, through their subsetting, calculation of basic indexes (such as mg# or A/CNK values) or cationic parameters (after Niggli, Debon & Le Fort and De la Roche), to normative recalculations (e.g., CIP

Classical Plotsle, e.g. Harker plots), ternary plots or spiderplots. Practical exercises illustrating the general principles are also included. Special attention is given to dealing with spurious correlations in binary plots (closure effect). The fundamentals and implementation of classification and geotectonic di

Specialized Plots and comprehensive; instead it focuses on arguably the most useful or interesting among them that could be suitable for common applications in igneous geochemistry. These include log–log binary plots (for discussing ratios), spiderplots colour coded according some independent variables (such as sili

GEN

Radiogenic Isotopesticular emphasis on Sr–Nd–Hf–Os isotopic systems. The text is concerned with calculation of initial ratios, ages ε and γ values, single- and two-stage model ages and fitting of isochrons. Practical exercises illustrating the principles on real datasets are also included. Lastly, the SrNd plugin is i
