5.1 Formation
Granulite is a fine-grained granular metamorphic rock in which the main component minerals are feldspars and quartz and forms at high temperature and pressure conditions.
Icelandite 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.

Granulite vs Icelandite 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 Granulite and Icelandite Reserves. Granulite is fine to medium grained metamorphic rock with a granular of polygonal crystals.. Icelandite belongs to volcanic igneous rocks which is rich in iron and belongs to andesite rock. 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 Granulite vs Icelandite information and Granulite vs Icelandite characteristics in the upcoming sections.

Granulite vs Icelandite 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. Granulite vs Icelandite characteristics assist us to distinguish and recognize rocks.
