Is marble more or less porous than granite?

    Marble is less porous than granite. Granite is a nice solid mix of different minerals, giving it the characteristic speckled look. Marble is a non-foliated rock type meaning it is generally impermeable.

    It really depends on the granite and on the marble. There are plenty examples of each that are rather porous, as well as examples that are quite impermeable.
