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 a dark colored fine grained igneous rock composed mainly of plagioclase and pyroxene minerals.
Basalt is a common extrusive igneous rock formed by the rapid cooling of basaltic lava exposed at or very near the surface of earth.
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.
Basalt is an aphanitic fine grained igneous rock that is relatively low in silica and alkali metals it has less than 10 feldspathoid by volume with at least 65 of the rock consisting of feldspar in the form of plagioclase this places basalt in the basalt andesite field of the qapf diagram basalt is further distinguished from andesite by its silica content of less than 52.
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.
Properties of rock is another aspect for granite vs basalt.
On moh s hardness scale the hardness of these.
The hardness of granite is 6 7 and that of basalt is 6.
Basalt is available in black brown light to dark grey colors.
