Silicosis Conditions UCSF Health

Silicosis is a lung disease caused by the inhalation of crystalline silica dust. Silica is a common mineral found naturally in sand and rock, such as granite and sandstone. Silica exposure is common in mines and quarries and in a number of other occupations such as construction (especially sandblasting), foundry-work, ceramics and glass-making.

Silicosis control guideline - Control guidelines

Silica (silicon dioxide) is among the most abundant compounds in the Earth’s surface. It is found in the form of quartz and other minerals, and is a major component of sand and rocks such as sandstone (67%), granite (25-40%) and shale (22%). Engineered stone products can contain up to 97% silica.

Everything You Need to Know About Sandstone

Aug 14, 2019  Sandstone Basics . Sandstone is a type of rock made from sediment — a sedimentary rock. The sediment particles are clasts, or pieces, of minerals and fragments of rock, thus sandstone is a clastic sedimentary rock. It is composed mostly of sand particles, which are of medium size; therefore, sandstone is a medium-grained clastic sedimentary ...

The principal stone worked was a very high-quartz sandstone, derived from the local Craigleith quarry, having properties that made it desirable for prestige buildings. However, even before the construction of the New Town, Craigleith sandstone was notorious for its dustiness and the Edinburgh stonemasons worked the stone in unventilated sheds.

Sandstone - Wikipedia

Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains. Sandstones make up about 20 to 25 percent of all sedimentary rocks. Most sandstone is composed of quartz or feldspar (both silicates) because they are the most resistant minerals to weathering processes at the Earth's surface, as seen in the Goldich dissolution series.
