Friable sandstone structural blocks - Nieto, Alberto

At the same time that the sand is being compressed, water trickling through the higher deposits carries minerals down, and these minerals start to glue the sand together. Left undisturbed long enough, sandstone will form as the mineral cement hardens. Young sandstone is very friable and crumbly, while mature rock can be extremely strong, in ...

Sandstone - Wikipedia

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.

Info Sandstone - How is it Formed?

Once the geological characteristics of a sandstone have been established, it can then be assigned to one of three broad groups: arkos or arkosic sandstones, which have a high (>25%) feldspar content and a composition similar to granite.; quartzose sandstones, also known as "beach sand", which have a high (>90%) quartz content. Sometimes these sandstones are termed "orthoquartzites", e.g., the ...
