You could check out the wiki, check out a past test and start trying to understand the questions, and/or start looking up info about every section of the rules.

Hey guys
I got placed into geologic mapping in my school tryouts and I have no clue where and how to start studying. Can anyone offer good sites to help me study? Also, do the soinc cds help?

No clue about the CDs though. They're generally helpful, but I'm not sure about the Geologic Mapping one.

Last year's dynamic planet covers A LOT of what you need to know, so you can find that in the wiki here. Thoroughly going through plate tectonics covers most of the geology that's tested. You can test your mapping by taking practice tests, and then looking up Youtube on what you don't know. And, as always, read the wiki.

Can anyone help me understand what a stereonet is? The rules say to bring one with tracing paper and pin, but I am just really confused in general about what it is/how to use it. From what I understand so far, it creates some type of projection, but how do I get one and how do I use it? Does anyone have any good resources on this?

Thanks!

A stereographic net is a piece of gridded paper that helps you project a sphere (the Earth) to a plane (a map).

I remember that second link, I found it really useful! There are also two posts I made on the first page about this.
See: viewtopic.php?f=285&t=12238#p359155 (pointing out youtube has lots of great examples for the process looks like *in practice*)
See: viewtopic.php?f=285&t=12238#p359151 ("Printing off stereonet" and "Other things you'll need" for examples of what to get)

I'm of the view that you shouldn't get all flustered with "projections" and all the vocab at first. It IS the fundamental concept and helps you think about maps and such, but I hope this helps on the "where to get it and use it" side. You might still have to know some minimal vocab like "plotting a plane with a strike and dip", but I think those are a lot more doable starting out.

What is meant by "major structural elements" in the rules? What topics would this cover?

Fantastic question! I think I went into this a little (like just one bullet) on the last page when discussing that there are "different geologic structures" and how you have to think about them *geometrically*: viewtopic.php?f=285&t=12238#p362289

There I discuss how different "structures" exist in geology (e.g. folds, faults, beds of rock, etc), and you can characterize different features or parts of these structures by their *geometry* (into planes, lines, and points). Unless I'm mistaken, the different geometric features are typically called "structural elements". I found folds were a good way of showing how a common geologic structure can be broken up into these different parts (you can search for "fold elements", "fold structure", etc and hopefully see examples and diagrams of this). Beyond this, I believe "geology structural elements" can be googled.

Are these explanations confusing / do you still not know what to look for? I wasn't sure, did this explain "what topics would this cover"? Hope this helps!
