Hardness, Elasticity, Porosity, Permeability, Density,
resistance to diagenesis, conditions of formation.
Generalities (this means that in general the following are true
and rules don't follow the exception if any exist)
Hardness: marble is harder than limestone. It has a higher
compressive strength and cohesion. This can get much more technical
so let's leave it at that.
Elasticity: Young's Modulus, shear modulus of marble is higher.
Bulk modulus and poisson's ratio of marble is lower.
Porosity of marble is lower.
Permeability of marble is lower.
Density of marble is higher.
Limestone is often altered via fluids and chemical underground
and marble isn't.
Marble is metamorphic rock and limestone in sedimentary.
Marble and Limestone are spelled different.
