What Is The Hardness Of Shale

Conversion of Hardness - Valve Magazine

Hardness is not a fundamental property of a material. In other words, it is not a property like density or elastic modulus. In the case of fundamental properties, conversion factors from one scale to another (such as from pounds per cubic inch to grams per cubic centimeter for density, or pounds per square inch to megapascals for tensile strength) involve simple unit conversion that can be as .

Shale - Wikipedia

Shale is a fine-grained, clastic sedimentary rock composed of mud that is a mix of flakes of clay minerals and tiny fragments (silt-sized particles) of other minerals, especially quartz and calcite. Shale is characterized by breaks along thin laminae or parallel layering or bedding less than one centimeter in thickness, called fissility.

The Moh's Hardness scale is not a linear scale unlike the scale of absolute hardness. So Orthoclase at 6 is not twice as hard as Calcite at 3, nor is the difference between talc and gypsum the same as the difference between Corundum and Diamond. An absolute hardness scale gives a clearer idea of how hard the minerals are in relation to each other.

It does this by changing from a shale to an argillite (and if you increase the P-T setting even further, it'll change from an argillite to a slate). Because argillite is a rock, and is therefore compositionally heterogeneous in its mineral assemblage, it does not have a defined hardness on the Mohs scale.
