Michaelmas: Week 6
Essay: Describe, using appropriate examples, how basaltic and granitic magmas are generated, the different tectonic environments in which these processes occur, and the type of rocks formed as a result.
Thin sections: Describe the thin sections ‘super 3’ and ‘super 7’. Refer to the short guide I have written to help you. These sections are in an envelope in my department pigeon hole (outside reception, on the left) – please be very careful with them and put them back in the envelope and back in my pigeon hole after you have finished working with them.
Remember that after identifying phases you need to decide what type of rock you are looking at, and give a summary of its history.
