A Volcanic Record Through Time part of MARGINS Data in the Classroom:MARGINS Mini-Lessons
This is a lecture that can be used - or adapted for use - in undergraduate geoscience classes. The goal of the lecture is to familiarize students with the concept of volcanic change through time at tectonic time scale commensurate to plate tectonic change. The lecture should follow lectures on rocks, minerals, Earth's layers and simple plate tectonics and Earth's Cenozoic evolution. A discussion can be incorporated on what information can be gained and on what Earth question can be addressed by studying long-term volcanic evolution. The lesson uses an example from Margins Subduction Factory Initiatives in order to illustrate possibilities, problems, limitations and outcome of obtaining a rock record through the life on a volcanic arc.
