Basalt Granite Hardness

Basalt is usually much finer grained than granite so it would be virtually impossible to determine the hardness of the individual mineral crystals.

Basalt granite hardness. Basalt is higher in rock hardness than that of coarser grained igneous rocks like granite compressive strength mpa 100 300 tensile strength mpa 10 30 shear strength mpa 20 60 bulk density. The hardness of granite is 6 7 and that of basalt is 6. Basalt is a common extrusive igneous rock formed by the rapid cooling of basaltic lava exposed at or very near the surface of earth. Basalt is available in black brown light to dark grey colors.

Basalt is a dark colored fine grained igneous rock composed mainly of plagioclase and pyroxene minerals. The streak of a rock is the color of powder produced when it is dragged across an unweathered surface. Granite is available in black grey orange pink white colors whereas basalt is available in black brown light to dark grey colors. Properties of rock is another aspect for granite vs basalt.

It most commonly forms as an extrusive rock such as a lava flow but can also form in small intrusive bodies such as an igneous dike or a thin sill it has a composition similar to gabbro the difference between basalt and gabbro is that basalt is a fine grained rock while. The streak of basalt is white to grey.
