Granite is extremely resistant and sandstone a little less so due to the percentage of quartz that each rock type contains.
It has been used for thousands of years and is regarded as a symbol of status strength.
Any unique combination of chemical composition mineralogy grain size texture or other distinguishing characteristics can describe a rock type.
Students of granites classify them in three or four categories.
It is the most common plutonic rock of the earth s crust forming by the cooling of magma silicate melt at depth.
Granites can be predominantly white pink or gray in color depending on their mineralogy the word granite comes from the latin granum a grain in reference to the coarse grained structure of such a completely crystalline rock.
