5 Formation
5.1 Formation
Kenyte 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.
Dacitic magma is formed by the subduction of young oceanic crust under a thick felsic continental plate. Further, the Oceanic crust is hydrothermally altered as quartz and sodium are added.

Kenyte vs Dacite 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 Kenyte and Dacite Reserves. Kenyte is a variety of porphyritic phonolite or trachyte rock with rhomb shaped phenocrysts of anorthoclase with variable olivine and augite in a glassy matrix. Dacite is a volcanic igneous rock which is rintermediate in composition between andesite and rhyolite. 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 Kenyte vs Dacite information and Kenyte vs Dacite characteristics in the upcoming sections.

Kenyte vs Dacite 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. Kenyte vs Dacite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Kenyte and Properties of Dacite. Learn more about Kenyte vs Dacite in the next section. The interior uses of Kenyte include Decorative aggregates, Entryways, Homes, Interior decoration and Kitchens whereas the interior uses of Dacite include Decorative aggregates, Entryways and Interior decoration.
