    Sand and Sandstone

    Sandstones consist largely of quartz grains and are held together by some natural cement or matrix such as calcium carbonate, iron oxide, silica cement, or clay Sandstone is ,Sandstone is a sedimentary rock It is formed by compaction and consolidation of sand, which is together by a natural cementing material, such as silica.

    Silica

    The term 'silica' can be misleading It is important to understand the difference between 'silica mineral', 'silicates', and 'silica glass' Quartz is the best example of a natural mineral that is almost pure silicon dioxide (it is the most abundant mineral on planet earth)Abstract Quartz cement as syntaxial overgrowths is one of the two most abundant cements in sandston The main factors that control the amount of quartz cement in sandstones are: framework composition; residence time in the "silica mobility window".

    Sandstone

    Sandstone Sandstone is a sedimentary rock formed from cemented sand-sized clasts The cement that binds the clasts can vary from clay minerals to calcite, silica or iron oxidSilica cemented sandstone is very durable and hard Calcite cemented sandstone is subject to acidic dissolution and is more easily eroded Clay and gypsum cements, which are soft minerals, tend to produce much softer sandstone and the sand can sometimes be rubbed off in a person's hands.

    Silica

    Silica is a mineral found naturally in sandstone, clay, and granite, as well as in parts of plants and animals, and is used as a versatile ingredient in the cosmetics and skin care industry because of its ability to serve as a an abrasive, anticaking agent, bulking agent, opacifying agent and suspending agentSilica cement, also called quartz cement, creates the strongest and most durable type of sandstone used for building The cement is a result of the quartz grains overgrowing and expanding the crystallized forms until it runs into another quartz crystal.
