Finegrained and lower porosity igneous rocks, such as basalt and diabase (dolerite) are generally higher in rock hardness than that of coarser grained igneous rocks, such as granite, diorite, and gabbro. As a result, the mineral grains of finegrained igneous rocks are more tightly held together than that of coarsegrained igneous rocks.

Basalt is from a melt that cooled very rapidly in other words, on the surface of the earth or in the ocean. When basalt is broken, it leaves very sharp edges. The finer the grains, the sharper these edges can be with the most extreme being obsidian (volcanic glass), which can form from either basaltic or .

Dolerite forms this way because the magma cooled from the outside toward the centre surrounded by more or less consistent temperatures. These joints radiate outward from the centre of each column, which themselves form perpendicular to the flow base of the source magma (or lava if the rock was extruded at the surface, such as basalt).
