hardness of granite rock

Granite is found in all continents around the world and is generally the foundation of many orogenic belts or mountain chains Most often granite is the underlying rock upon which sedimentary and other continental rocks rest Granite is found in batholiths or large magma plumes that The hardness of stone is measured by Mohs hardness as a unit of calculation Mohs hardness in the 6~7 (F=14~20) are hard stone such as Quartzite and Granite Mohs hardness between 3 to 5 (F=8~14) belong to the medium-hard stone such as Marble Mohs hardness in 1~2 (F=2~6) are soft stone such as limestone and dolomite etc
