Quartzite |
||
| The parent rock for quartzite is quartz-rich sandstone. As sandstone becomes deeply buried, rising temperature will fuse the quartz grains together forming the extremely hard and weather-resistant rock quartzite.Like marble, quartzite comes in many colours, but when pure it is light-coloured.Quartzite tends to have a sugary appearance, and when broken the fractures cut through the sand grains, not around them as with a sandstone.
Quartzite is a very strong stone but is difficult to work. Because quartzite has a limited colour range and is not often found in large bodies suited for quarrying, the building industry prefers granite for demanding applications. |
