5 Formation
5.1 Formation
Arkose rock forms from the weathering of feldspar-rich igneous or metamorphic rock, most commonly granitic rocks, which are primarily composed of quartz and feldspar.
Foidolites is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

Arkose vs Foidolite 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 Arkose and Foidolite Reserves. Arkose is a sedimentary rock, specifically a type of sandstone containing at least 25% feldspar. Foidolite is a rare type of coarse-grained intrusive igneous rock with a feldspathoid mineral content greater than 60%. 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 Arkose vs Foidolite information and Arkose vs Foidolite characteristics in the upcoming sections.

Arkose vs Foidolite 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. Arkose vs Foidolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Arkose and Properties of Foidolite. Learn more about Arkose vs Foidolite in the next section.
