Porosity

The total porosity of the granodiorite sample is 3.05%, the opened porosity is 0.91%. Basically, pores are of subcapillary and capillary size (15–40 μm), there are single pores with a diameter of more

than 100 μm. The predominant shape of pores is close to spherical (sphericity factor is 0.80). The void density is 2.06 mm<sup>−</sup>3.
