The common textural terms used for rock types with respect to the size of the grains or crystals, are given in the Table. The particle-size categories are derived from the Udden-Wentworth scale developed for sediment. For igneous and metamorphic rocks, the terms are generally used as modifiers—e.g., medium-grained granite.

Reducing the roughness of rock tablets can lead to unnatural smooth or even polished (i.e., glossy) surfaces. Furthermore, rock porosity is an important weathering control, that determines the rock specific surface (Brantley and Mellott, 2000; Orkoula and Koutsoukos, 2001).
Dissolution of natural stone such as marble is not limited to its surface. The porous structure, known to play an important role in stone decay, is also affected by the conditions of dissolution. ...
