Hey, so I'm having trouble with what to study, I went to an invitational a couple days ago and I was completely thrown off guard? For example they asked something about plutonic can someone please help?
Well, make sure you understand the rock cycle in depth (e.g. the term "plutonic" is synonymous to "intrusive" in the context of igneous rocks).
Make sure you have information about characteristics, uses, etc. of all of the rocks and minerals on the list in your binder: https://www.soinc.org/sites/default/fil ... lsList.pdf
Be able to identify all of them. I'd strongly recommend trying to get real specimens of them if possible to practice this.
Make sure you understand relationships between the rocks and minerals listed (e.g. how is each variety of quartz different from one another? What is the parent rock for each metamorphic rock? Which minerals are present in each igneous rock?)
