Re: Rocks & Minerals B/C
Dunno if this helps, but I did a quick search. I know there is an exhaustive but clear explanation (at least one ) of Bowen's out there that I've used as a reference before, but I don't have a clue where I got it. So...
Here you have a simple treatment of the igneous rock groups formed including a figure that may help. Scroll down to section B here for a little more information. Lastly, the first few slides in this lecture may be helpful. Ignore the thermo garbage in the end...slide 5 is the one I want to direct your attention to.
That help?
EDIT: Did some digging through my stuff and found this. You want page 10 (or Ctrl+F to Bowen's). I think points 10 and 11 are relevant to what you're after, though the rest is all good, of course.

Re: Rocks & Minerals B/C
Has anyone ever had a question about Brinell hardness before? As opposed to the traditional Moh's hardness scale.

Re: Rocks & Minerals B/C
I have not and I doubt it will ever be asked because "the conditions of the test used to obtain the number must be specified" and that would create some variance and ultimately be harder to grade for the proctor.

Re: Rocks & Minerals B/C
Has anyone ever had a question that asked where specific rocks or minerals could be found in the world? Just wondering in case I should know.

Hornblende is a variety of amphibole and amphibole is a family that's just not on our listwufactor2012 wrote:Does anyone know any varieties of kaolinite or hornblende?
i assumed kaolinite doesn't have any varieties, if you count clay?
So far...medaling has been a rollercoaster
but hopefully, next one would be on top!

Re: Rocks & Minerals B/C
Not in that exact wording, no. Mainly, I think, because there are many places to find minerals, and many minerals can be found in multiple locations. However, there was a question once about where a mineral was found in the US, so yes. I think the locations would be a given to have in your binder.darkdeserthighway wrote:Has anyone ever had a question that asked where specific rocks or minerals could be found in the world?

Re: Rocks & Minerals B/C
I agree with Allinea, as I have had questions about which countries that produce a certain minerals in the highest quantities as well as famous localities for certain rocks.Allinea wrote:Not in that exact wording, no.

Re: Rocks & Minerals B/C
When identifying mineral samples with multiple minerals in each sample, or just idenifying single minerals in general, what do you guys look for first? Because we all know color is not reliable.
