Does anyone know where I can download software to plot geochemical data of an igneous-derived metamorphic rock (i.e., granitic gneiss) using Streckeisen and De La Roche diagrams? Thanks in advance
You can easily install GCDkit from https://www.gcdkit.org/download and then use "Tab Plots" to plot geochemical data diagrams for both intrusive and volcanic rocks.
It seems that the program is not very easy to use. First, you have to install R and then program using command strings. It’s not user-friendly at all! Is there an equivalent with a Windows interface?
