It's study questions
Thu, 07/05/2012 - 18:39It's study questions constructed by my teacher in Geology (based upon the book "Earth; portrait of a planet"). I can't find the meaning of "mineral A" nor "mineral B" in the book. Are these some sort of definitions or ways of classifying minerals similar to the way in which carbon are called mineral C?

Depends on the form.
Thu, 07/05/2012 - 22:04Depends on the form. Graphite is {001} Basal (i.e. along flat planes), diamond is octohedral {111}...
Actually, I'd better check those:
http://www.minerals.net/mineral/graphite.aspx
http://www.minerals.net/mineral/diamond.aspx
Yep, that agrees with my memory, so probably correct (my memory, not the site).

What you have listed are
Thu, 07/05/2012 - 23:09What you have listed are sections where various minerals are classified.
Perhaps the best thing would be to write out or scan the whole question and post it here. We may be able to help then.

Thank's but I managed to
Fri, 07/06/2012 - 16:33Thank's but I managed to figure it out on my own. Mineral A was Quartz and Mineral B was Calcite!
However, I have another question; What type of magmatic phenomena can be seen by 37.745 N 119.535 W and what type of magmatic rock does it consist of?

Mineral A and B?
Submitted by Kajsa1990 on Thu, 07/05/2012 - 17:48.When one talks about "mineral A" and "mineral B", what does that refer to? I know that Mineral C refers to Graphite/Diamond.
It's in this context;
What is the crystal habit of mineral A?
What is the hardness of mineral B?
