Formation of Siltstone

Formation
Siltstone is a type of sedimentary rock which is formed from fine rock particles. As the particles of eroded rock travel along with water, the edges of the rock are worn-out by water into a rounded shape.

Information about Siltstone

Rocks are naturally occurring solids which are composed of minerals & have been used by humans since ages. From Stone Age, rocks are used for various purposes. Also, the metals and minerals found in rock play an important role in our life. Get to know all the Siltstone Uses. We have provided you with all information about Siltstone rock here. Siltstone can be defined as a fine-grained sedimentary rock which mainly consists of consolidated silt. Siltstone is available in brown, red, reddish brown colors. The streak of a rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Siltstone is white. Get to know more about Siltstone rock and characteristics of Siltstone rock in the next sections.

Characteristics of Siltstone

Many rocks have distinct characteristics. Some of the Properties of Siltstone are hardness, structure, streak, fracture etc. Siltstone is significant as it is composed of minerals and has variety of uses in our day to day life. The characteristics of Siltstone plays an important role in its identification. The hardness of Siltstone is 6-7 on Moh’s hardness scale. Rocks according to their hardness are divided into:Hard Rocks, Soft Rocks and Rocks with Medium Hardness. Fracture of Siltstone rock is conchoidal. Its specific heat capacity is Not Available. Siltstone is heat resistant, impact resistant, pressure resistant, water resistant. Some of its uses are:

More About Siltstone

Siltstone is a type of Sedimentary Rocks. The color of rock is one of its important property. Siltstone rock is available in brown, red, reddish brown colors. It is Rough in appearance. The Siltstone mineral content includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz, Sand, Silica, Silt. Its compound content includes Aluminium Oxide, CaO, Iron(III) Oxide, Potassium Oxide, MgO, Sodium Oxide, Silicon Dioxide. Let’s move on to the types of Siltstone. Siltstone rock does not have any types. Fossils are the remains of prehistoric plants or animals which are embedded in rock and preserved in petrified form. Fossils are found only in sedimentary rocks. As Siltstone belongs to Sedimentary Rocks, fossils are found in it.
