Oh, dude, basalt has a hardness of around 6 on the Mohs scale. It's not the softest thing out there, but it's not exactly diamond-level tough either. So, like, if you're thinking of using it to scratch your back, maybe stick to a loofah instead.

What is the hardness of basalt rock?

Plagioclase feldspars which are a component of basalt has a hardness of around 7 on the Mohs Scale.


Is marble harder than basalt?

No, basalt is generally harder than marble. Basalt is a mafic extrusive rock that has a higher hardness and durability compared to marble, which is a metamorphic rock.


How hard is basalt?

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 (Mg/m3) 2.8-2.9 Porosity % 0.1-1.0


Which is harder basalt or granite?

Both basalt and granite are types of rock, and a rock is composed of multiple minerals - except for some rocks composed of essentially one mineral like limestone (calcite) or quartzite (quartz). Minerals are crystalline compounds with known characteristics such as hardness, specific gravity, etc Therefore the hardness of the rock depends on the exact location on the rock you are testing the hardness, as it will vary from mineral to mineral. Some minerals even have differential hardness. Granite is composed of quartz, feldspar, and usually some ferromagnesian minerals such as biotite or hornblende (depending on the definition of a granite). Basalt is composed mostly of plagioclase (a feldspar) and pyroxene. Each of those minerals has a different hardness, and geologists never use the hardness of a "rock" to determine what kind of rock it is. Basalt is usually much finer grained than granite so it would be virtually impossible to determine the hardness of the individual mineral crystals. On Moh's hardness scale, the hardness of these rock-forming minerals are as follows: Quartz 7 Feldspar 6 (depending on the species of feldspar) Biotite 2.5-3 Pyroxene 5-6 (depending on the species of pyroxene) So the hardness of a rock is determined by the minerals, and in a coarse grained rock like a granite, the hardness can vary widely. The hardest mineral in granite (quartz) is harder than the hardest mineral in basalt (feldspar), but that's not enough to say that granite is conclusively harder than basalt. The resistance to breaking of a rock (which could be confused with the apparent hardness to a non-expert) is greatly affected by fractures, weathering, induration, welding, and many other features which are independent of mineral content.


What is the hardness of gabbro in mohs hardness scale?

A rock's hardness is usually measured in compressive fracture strength rather than a Mohs hardness which measures a mineral's relative hardness in comparison to other minerals. ASTM standard tests have rated gneiss at 50-200 MPa (roughly 350-1400 psi), a range lower than slate, quartzite, or basalt.

What is the mohs scale for Feldspar?

Basalt scores an 8 on the Moh's scale. This makes it harder than quartz and vanadium, but weaker than boron and titanium carbide. It can easily scratch steel and glass. It is just about as hard as topaz. Basalt is also an igneous rock, formed by hardened lava, which explains why it is so hard.


Which crusher should be used for which rock?

Generally, different crushers are chosen according to hardness of stone. Cone crushers are suitable for high hardness stone such as marble, granite, basalt and so on. Impact crushers are suitable for soft stone such as gypsum, limestone and so on.

What is the hardness of a volcanic rock?

Volcanic rocks can vary in hardness depending on their mineral composition. On the Mohs scale of mineral hardness, most volcanic rocks fall between 5 to 7, with basalt being around 6 and rhyolite around 7.
