Rocks and Minerals B/C

[Unome]

Does anyone know a really good field guide I should base my notes off of? Can someone let me just have a peak at their binder cause I never chose an event where you could use a binder? Is their a limit on how many pages the binder may have?

There's a pretty good description of field guides on the wiki; others on this thread can probably give you more info about this as well. The rules manual specifically mentions that the binder may be any size (this is almost universally taken to mean any amount of pages as well, and it would take a lot of time for event supervisors to check); historically there has never been a limit on binder size for events allowing a binder, and this seems likely to continue into the foreseeable future.

Is there a good way to distinguish between pink mica and lepidolite? Thanks!

To my knowledge the pink color in lepidolite is from the element lithium, so they are the exact same thing (I could be wrong on that). Do you have any images you could post on here?

Sorry, I meant pink muscovite ^^"

I was working on my lepidolite page using this: http://www.minerals.net/mineral/lepidolite.aspx

Then when I got to the distinguishing similar minerals part, all it said for Pink Muscovite was "Very difficult to distinguish from Lepidolite." But no advice on how to distinguish them apart.

So I wondering if any of you guys could help me with it

Can't say for certain, as having a diverse binder is important and what is in your binder should be based on personal preferences. If only one thing, I'd say personal descriptions of the samples including general information about them.

Anyone know how to visually and physically differentiate between chalk and diatomite?

Does anyone know how microcline forms? I'm trouble finding any good information on it.

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?)
