There is no such thing as "mountain mana" or "plains mana". There are only the basic land types, Mountain and Plains, and the colours of mana, red and white.
How do you tell if something's a Mountain or a Plains? Just check the type line. If it says "Land - Mountain", then it's a Mountain.
So, you can use Arid Mesa to fetch a basic Mountain, or you can use it to fetch a Madblind Mountain, or a Sacred Foundry, or a Stomping Grounds, since they all have the "Mountain" subtype. However, it can't fetch, for example, Valakut, the Molten Pinnacle, or Battlefield Forge.
