Formation

Formation
Dunite is a plutonic ultramafic igneous rock consisting almost m olivine. It can be formed in two ways.   
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.

Dunite vs Kenyte 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 Dunite and Kenyte Reserves. Dunite is a green to brownish coarse-grained igneous rock mainly consisting of olivine. 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. 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 Dunite vs Kenyte information and Dunite vs Kenyte characteristics in the upcoming sections.
