Cores of other sandstone types fracture with sharp edges or shatter into small sharp fragments. Crystallized Sandstones are white and sugary and, in many cases, very hard and brittle. In some examples of this type, the grains are welded together and the cored rock has a smooth, polished appearance ( e.g. 23R ).

 · Sandstone. An agglomerated stone, sandstone consists of sand held together by cement of a variable nature. Sandstone consists mainly of quartz grains, is resistant to compression, and has variable flexibility. Low to intermediate strength sandstone crumbles more easily while the higher strength sandstones are more strongly cemented.

Sandstone: Sedimentary Rock

Types of Sand Grains. The grains in a sandstone can be composed of mineral, rock, or organic materials. Which and in what percentage depends upon their source and how they were altered during transport. Mineral grains in sandstones are usually quartz. Sometimes the quartz content of these sands can be very high - up to 90% or more.

Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains. Sandstones comprise about 20–25% 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.

QUARTZITE. This is an amazing material. It is naturally strong, resists heat and is hard to stain. Quartzite is formed from sandstone and quartz together under a great deal of heat and pressure. The empty grains of sandstone are filled with quartz. This process makes quartzite harder than quartz. View colors available at Stone Surfaces.
