Sandstone-C



Sandstone!!! //**Marina Meyers **//  ﻿﻿ The type of sedimentary rock is clastic. It forms in cliffs, ridges, rivers, oceans, glacier, desert deposits, and lots of other places similar to what has been listed.

It forms by accumulating deposits of sand from wind or water deposition are initially created. The weight from the deposits above cause compaction of the lower deposits. Compaction forces out air and water that exists between the sand grains. Minerals form from the remaining concentrated solutions in a process called precipitation.These minerals act as cement which connects the particles together creating sandstone. Or in other words...Erosion. Then Deposition. Then Compaction. Then at last Cementation. Then to be found and used for something.

The minerals found in it are quartz, feldspars, micas, calcite, and clays.

The grain size is small-medium because i grains are sand grain sized (most of the time).

The grain shape is both rounded and angular.

It is normally uniform because they typically look and stay the same.

It normally doesn't contain any fossils because the energetic environments where sand beds form don't favor their preservation, but it can have sea shells and other living creatures in it.

It can be used for building material, decorative stones, tiles, tombstones, monuments, roads, ore of silica for glass, abrasives, aquifers, petroleum reservoirs, and many more other things. (more under extra facts)

Its color can vary in many different ways. From yellow to orange, and from gray to pink, and lots more.

It is related to shale, conglomerate, siltstone, and breccia.

Because of its hardness, sandstone is often used to make grindstone wheels.

There are 3 broad groups of sandstone: arkosic, quartzose and argillaceous.

The fine grain of sandstone allows running water to filter out pollutants from the rock. Sandstone formations, like the Navajo Sandstone in the Southwestern US, can grow to 2000 feet.

Environments where large amounts of sand can accumulate include beaches, deserts, flood plains and deltas.

Some sandstones are resistant to weathering, yet are easy to work.

The most common colors are tan, brown, yellow, red, gray and white. Since sandstone beds often form in highly visible cliffs and other topographic features, certain colors of sandstone have been strongly identified with certain regions.

They can make sandstone countertops, candle holders, bricks, tiles, sculptures, tombstones, carvings, coasters, paving,pebbles, clocks, bowls, art, etc...

Sandstone is mainly made from hte minerals quarts and feldspars.

There are different types of sandstone. One of which is Collyhurst sandstone that has been used for building in North West England.

Sandstone can be called perhaps the best sedimentary rock because it is very commonly found.
