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.
Basalt granite hardness.
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 basalt is white to grey.
The hardness of granite is 6 7 and that of basalt is 6.
Granite is available in black grey orange pink white colors whereas 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.
Basalt is available in black brown light to dark grey colors.
On moh s hardness scale the hardness of these.
The streak of a rock is the color of powder produced when it is dragged across an unweathered surface.
Basalt is usually much finer grained than granite so it would be virtually impossible to determine the hardness of the individual mineral crystals.
Appearance of granite is veined or pebbled and that of basalt is dull and soft.
