'der Granit' and 'der Basalt' are both very hard types of rock. That is why they can easily be confused, especially if you are only thinking of hard building material. 'Granit' is often lighter or speckled and is frequently used for stairs, slabs, or monuments. 'Basalt' is a dark volcanic rock that forms from lava. If the volcanic origin or the dark color is important, 'Basalt' is more precise. If you mean the well-known hard stone used in construction or monuments, 'Granit' often fits.
