Answer:
I believe the correct answer is a mixture. Most rocks are just different compounds or elements somewhat fused through heat and pressure. The substances are not chemically bonded together which means that they all retain their chemical identity and therefore can be separated by breaking them up. A good example of this is granite where you can see the different compounds that got fused together and can falls apart when you grind it. I hope this helps. Let me know if anything is unclear.

Explanation:
For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.
Here magnesium is having an oxidation state of +2 called as 
cation and bromine 
is an anion with oxidation state of -1. Thus they combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral .
The cations and anions being oppositely charged attract each other through strong coloumbic forces and form an ionic bond.
