Archaeological Significance
Formation
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.
Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.

More about Icelandite and Laterite
Here you can know more about Icelandite and Laterite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Icelandite and Laterite consists of mineral content and compound content. The mineral content of Icelandite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite, Magnetite, Plagioclase, Pyroxene, Quartz, Zircon and mineral content of Laterite includes Aluminum Oxides, Biotite, Hematite, Hornblade, Iron Oxides, Manganese Oxides, Micas, Muscovite or Illite, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Icelandite vs Laterite, the texture, color and appearance plays an important role in determining the type of rock. Icelandite is available in bluish - grey, grey, pink, yellow colors whereas, Laterite is available in brown, buff, red colors. Appearance of Icelandite is Dull and Soft and that of Laterite is Rough and Banded. Properties of rock is another aspect for Icelandite vs Laterite. The hardness of Icelandite is 7 and that of Laterite is 2. The types of Icelandite are Intermediate volcanic rock whereas types of Laterite are Laterite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Icelandite and Laterite is white. The specific heat capacity of Icelandite is 2.39 kJ/Kg K and that of Laterite is 0.92 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Icelandite is heat resistant, pressure resistant, scratch resistant, wear resistant whereas Laterite is heat resistant, pressure resistant.
