5 Formation
5.1 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.
Anorthosite is a phaneritic, intrusive igneous rock which is characterized by a predominance of plagioclase feldspar which is almost 90–100%, and a minimal mafic component.

Siltstone vs Anorthosite Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Siltstone and Anorthosite Reserves. Siltstone can be defined as a fine-grained sedimentary rock which mainly consists of consolidated silt. Anorthosite is a granular igneous rock composed largely of labradorite or plagioclase. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Siltstone vs Anorthosite information and Siltstone vs Anorthosite characteristics in the upcoming sections.

Siltstone vs Anorthosite Characteristics

Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Siltstone vs Anorthosite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Siltstone and Properties of Anorthosite. Learn more about Siltstone vs Anorthosite in the next section.
