Can granite be used to cultivate live rock?

Thanks for any inputs, and if not, what kind of rocks can be used for aquaculture. How is limestone rock different from granite?Or are they the same?Thanks again.

Any rock can be liverock, but good liverock should be porous to allow for maximum surface area for bacteria and critters. Animals need to be able to make holes in the stuff. If you look at good Fiji LR, it's often quite light per volume and breakable, I can often snap a piece in two with just my hands. I don't think you're gonna get that with granite.
