Description:

In this exercise, students use whole-rock major- and trace-element compositions of volcanic rocks to explore the origins of compositional variation in igneous suites. With the help of detailed step-by-step instructions, datasets from the Yellowstone and Crater Lake calderas are downloaded from the GEOROC database, imported into Excel spreadsheets, and graphed in the form of "Harker" diagrams to learn about the different petrogeneses of these two volcanic suites.
