Oct 19, 2017 · Hardness technically is the 'Resistance to permanent deformation'. The Mohs scale is relative, while Vickers, Rockwell, Brinell and Knoop are absolute measures of hardness. Mohs is a measure of scratch hardness, while the rest measure indentation. There is however a direct correlation between the two, because scratching involves two actions: 1.
Aug 23, 2018 · Difference Between Basalt and Granite What is Basalt? Basalt is an igneous, mafic, and volcanic rock which is produced by lava flows in many different volcano types. It contains mainly volcanic glass, pyroxene and plagioclase feldspar and is finegrained. Basalt is one of the most common types of rock on Earth as well as other planetary bodies in the Solar [.]
It occurs as a crusty lining in cavities in basalt and related rocks. Associated with zeolites, datolite, pectolite, and calcite. Has a characteristic green colour. Resembles hemimorphite but is of lower specific gravity and fuses easily. Proustite Proustite has the formula Ag3AsS3 and a relative hardness of 3. It is an ore of silver.
Jan 22, 2020 · Sandstone. – Shale. – Slate. – As you can see, rocks of the same type can have a range of densities. This is partly due to different rocks of the same type containing different proportions of minerals. Granite, for example, can have a quartz content anywhere between 20% and 60%.
1) Crushed basalt shapes quickly and polishes to a beautiful black color. Our favorite polish for basalt is TXP aluminum oxide.

It generally occurs in the hues of gray. However, it is lighter in color than basalt. It is said to form thicker fluxes or domeshaped structures. The hardness of andesite rock on Moh's scale is 7. Uses of Andesite Rock. 1) It finds its chief uses in the construction and roadmaking industries for making roadbeds.
Answer (1 of 3): Granite contains mainly quartz, feldspar and mica. Arguably, quartz is the hardest commonplace rockforming mineral. So, feldspar and mica are slightly softer than quartz and a rock containing only quartz should be harder. A good candidate would be .
