almandine, calcite, quartz ?

Think outside the box people! The only one right so far is quartz, and that's the one I thought nobody would get. Think: what two minerals are frequently found together?

Quartz is the matrix that the two minerals are in by the way.

Quartz, Apatite, and Feldspar?

No.. Keep trying! :p
And this isn't a ridiculous question, I actually encountered this at Wright state.
I'll compromise.. Just guess one right (besides quartz) and I'll give it to you.
