Quartz sandstone is not very easy to weathering
The sandstone is formed by clastic sediments, and biological sedimentary formation such as coal, and chemical deposition to form such as gypsum, Jasper, clastic rock or some other can be mineral crystals, these substances can be cemented detrital calcite, clay or silica, clastic particle size between 0.1-2 mm, if debris the size is too small to form schist or shale, the formation of conglomerate or breccia. Quartz is one of the oxides of silicon, and its chemical composition is SiO2, three. Translucent or opaque crystals, such as impurities that contain other minerals, show the color of the.
Some of the sandstones are resistant to weathering, but easy to cut, so they are often used as building materials and paving materials. The particles in the sandstone are relatively uniform and hard, so sandstone is often used as a grinding tool.Due to the good permeability of sandstone, the surface aquifer can filter out pollutants, more than other stones, such as limestone to resist pollution
No, not only weathering and wind action, the key is to have water corrosion, quartzite itself is very stable, hardness is also very large, generally only contain calcium carbonate rocks are more easily weathered.
Quartz has many variations, some of which are semi precious stones. Especially in Europe and the Middle East, quartz has been widely used in ancient times to make jewelry and hard stone carving.Quartz can also be used as one of the materials for making glass.
