Formation
Oil Shale forms on the beds of seas and lakes and its formation starts with the organic debris settling and accumulating at the bottom of a lake or sea which are then transformed into rock with the help of high temperature and pressure.
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.

The mineral content of Oil shale includes Albite, Biotite, Calcite, Chert, Chlorite, Dolomite, Hematite, Micas, Muscovite or Illite, Pyrite, Quartz, Silica, Sulfides 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 Oil shale vs Icelandite, the texture, color and appearance plays an important role in determining the type of rock. Oil shale is available in black, brown, buff, green, grey, red, yellow colors whereas, Icelandite is available in bluish - grey, grey, pink, yellow colors. Appearance of Oil shale is Muddy and that of Icelandite is Dull and Soft. Properties of rock is another aspect for Oil shale vs Icelandite. The hardness of Oil shale is 2-3 and that of Icelandite is 7. The types of Oil shale are Carbonate-rich Shale, Siliceous Shale and Cannel Shale 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 Oil shale and Icelandite is white. The specific heat capacity of Oil shale is 0.39 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.Oil shale is heat resistant, impact resistant whereas Icelandite is heat resistant, pressure resistant, scratch resistant, wear resistant.
