Formation
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.
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.

Conglomerate 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. Conglomerate vs Icelandite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Conglomerate and Properties of Icelandite. Learn more about Conglomerate vs Icelandite in the next section. The interior uses of Conglomerate include Decorative aggregates, Floor tiles and Homes whereas the interior uses of Icelandite include Decorative aggregates, Floor tiles, Homes, Interior decoration and Kitchens. Due to some exceptional properties of Conglomerate and Icelandite, they have various applications in construction industry. The uses of Conglomerate in construction industry include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Roadstone and that of Icelandite include Cobblestones, Construction aggregate, For road aggregate.
More about Conglomerate and Icelandite
Here you can know more about Conglomerate and Icelandite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Conglomerate and Icelandite consists of mineral content and compound content. The mineral content of Conglomerate includes Clay, Sand, Silica, Silt and mineral content of Icelandite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite, Magnetite, Plagioclase, Pyroxene, Quartz, Zircon. You can also check out the list of all Sedimentary Rocks. When we have to compare Conglomerate vs Icelandite, the texture, color and appearance plays an important role in determining the type of rock. Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors whereas, Icelandite is available in bluish - grey, grey, pink, yellow colors. Appearance of Conglomerate is Shiny and Rounded and that of Icelandite is Dull and Soft. Properties of rock is another aspect for Conglomerate vs Icelandite. The hardness of Conglomerate is 2-3 and that of Icelandite is 7. The types of Conglomerate are Not Available whereas types of Icelandite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Conglomerate and Icelandite is white. The specific heat capacity of Conglomerate is 0.92 kJ/Kg K and that of Icelandite is 2.39 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Conglomerate is heat resistant whereas Icelandite is heat resistant, pressure resistant, scratch resistant, wear resistant.
