The tutorials presented on this page will help the user in understanding the applications of the EC-RAXFC code. Before using the code the user should have some general knowledge about natural systems. A general understanding of partition coefficients of trace elements is useful, along with an understanding of crustal vs. mantle isotopic signatures. A basic understanding of the lithology and geothermal structure of the upper vs. lower crust is important in order to recognize the processes that the EC-RAXFC represents. The objectives of this code involve conceptualizing the idea of open system magmatic processes in the earth's crust. By observing the isotopic signatures and trace element concentrations during an event, it is possible to make connections between natural and simulated magmatic plumbing systems.
