Fine grained rock exhibits a non-visible or nearly non-visible crystalline structure on a fractured surface. On the opposite end, a coarse grained rock exhibits mineral crystals of the rock's constituents on a fractured surface. The larger the crystals, the coarser grained is the rock. Basalt would be an example of a fine grained rock. Granite would be an example of a coarse grained rock.
