Ganister vs Dunite


Definition

Definition
Dunite is a green to brownish coarse-grained igneous rock mainly consisting of olivine   
A ganister is a hard, fine-grained quartzose sandstone or orthoquartzite which is basically used in the manufacture of silica brick typically used to line furnaces and is a type of sedimentary rocks.

Formation

Formation
Dunite is a plutonic ultramafic igneous rock consisting almost m olivine. It can be formed in two ways.   
Ganisters are formed by the destruction of easily weathered minerals mainly feldspar, within the surface horizon of soil by soil-forming processes.

Dunite vs Ganister 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 Ganister Reserves. Dunite is a green to brownish coarse-grained igneous rock mainly consisting of olivine. A ganister is a hard, fine-grained quartzose sandstone or orthoquartzite which is basically used in the manufacture of silica brick typically used to line furnaces and is a type of sedimentary rocks.. 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 Ganister information and Dunite vs Ganister characteristics in the upcoming sections.
