May 06, 2007· So the hardness of a rock is determined by the minerals, and in a coarse grained rock like a granite, the hardness can vary widely. The hardest mineral in granite (quartz) is harder than the hardest mineral in basalt (feldspar), but that's not enough to say that granite is conclusively harder than basalt.
