Sandstone: Mineral information, data and localities.
A sandgrade the majority of sandstone can be classed as silicatesandstone. A mediumgrained clastic sedimentary rock composed of fragments of sand size ( diameter) set in a finegrained matrix (silt or clay) and more or less firmly united by a cementing material (commonly silica, iron oxide, or calcium carbonate); the consolidated equivalent of sand.

The Quartz Page: Quartz as a RockForming Mineral
The durability of quartz sandstone is determined by the minerals that fill out the voids between the grains. If this cement consists mainly of quartz, the rock will be chemically very stable. But very often the voids are filled with calcite and the rock weathers quickly, as this cement dissolves in rain water that percolates the rock.
quartzsandstone
Quartzsandstone is a sandstone consisting of more than 95% quartz clasts and below 5% matrix. Sandstone is a sedimentary rock formed by the cementation of grains of sand ( to 2 mm in diameter). Often this cementing material is calcium carbonate, but also silica or .
Sand mining Wikipedia
Sand mining is the extraction of sand, mainly through an open pit but sometimes mined from beaches and inland dunes or dredged from ocean and river is often used in manufacturing, for example as an abrasive or in is also used on icy and snowy roads, usually mixed with salt, to lower the melting point temperature on the road can replace eroded coastline.
