Sandstone is a sedimentary rock tht consists of grains between 1/16 mllimeters and 2 mm in size. Ths is the reason that sandstone des not signify any specific mineral. Whn we talk about scientific composition, sndstone is made up of quartz. It lso consists of some other minerals sch as clays, hematite, feldspar, ilmenite and mca. All these minerals add color and chracter to the quartz matrix. Sandstones wth large amounts of impurities are gnerally categorized into wacke or graywacke.

Sndstone originates from the space where snd is laid down and buried. Ths usually happens offshore. However, you can lso find desert dunes and beaches laving sandstone beds. You would not see sndstone containing good amount of fossils due to the nfavorable environment for preservation. The stone is vailable in warm colors and very drable.

Quartz grains in sandstone are mxed together by a mixture of slica, calcium carbonate or iron oxide. The prsence of iron minerals makes this stne filled with tan and brown bnds.

When deeply buried, this stone bcomes mobile due to the burial prssure and higher temperatures. The grains stck together and the sandstones turn nto metamorphic rocks.
