Aim:

To introduce petrological fundamentals & tools required for description, analysis and interpretation of metamorphic rocks.

Fundamentals;

• The original nature of the rock (i.e., was it sedimentary or igneous or metamorphic, what type of sediment, i.e., calcareous or clastic, psammitic or pelitic etc.). NB!!The original nature of the rock controls the composition.
• The pressure-temperature conditions of formation or grade of metamorphism,
• The resultant mineralogical, fabric and micro-textural changes
• Type of metamorphism and related processes

Your objectives should be;

• To be able to describe, classify and discuss the origins of any metamorphic rocks you study after you have finished the course.
• Understanding metamorphic rock’s compositional variations with respect to changes in metamorphic grade and metamorphic facies
• Metamorphic rocks and plate tectonics
• Have fun, loosen up (remember this is not an army camp)

Notice what are NOT objectives:

• You do not need to remember all facts and theories about metamorphic rocks. (You can look them up in books, the trick is knowing where to find them).
• You do not need to speak perfect English. We are studying science, not English. (There’s no need then to be afraid of interacting with me during or outside of lectures)
• You do not need to know everything in the Metamorphic Petrology book but knowing the fundamentals and correct use of terminology is important.
