| Abstract: | The Leeb D Hardness test uses the rebound of a semispherical penetrator to estimate the rock hardness. This method can be used in ornamental rocks, such as granites and marbles, as a expedite proxy to identify the main rock-forming mineral phases and mineral alteration processes (e.g. dolomitization and silicification on marbles), as well as to estimate the uniaxial compressive strength, through a correlation of both data. |
