Silica Sand

Silica (industrial) sands contain a high proportion of silica (normally, but not exclusively, more than 95% SiO2). It is recognised by government as an essential raw material of national importance and as such there is a requirement to provide an adequate and steady supply, through maintaining stocks of permitted reserves and safeguarding silica sand resources.

Sussing Out Sandstone

 · Sand can be deposited in vast blankets, such as in the Sahara desert. The Navajo Sandstone that spans Utah, Arizona, and Colorado tell us this was a Sahara-like desert during the Cretaceous Period. Massive cross beds, like those seen on sandstone cliffs in Zion National Park, are the remnants of huge sand dunes that marched across the desert floor.

Berea Grit Sandstone – Berea Historical Society

Because of its large sand grains, geologists believe that Berea Grit probably was deposited near the shore of an ancient lake. The sandstone found in Berea — the largest sandstone quarries in the world — is unique in that the grain runs the long way of the blocks, making it easier to quarry and more durable in its uses.
