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.
Andesite is a fine-grained igneous rock that forms when the magma is erupted onto the surface and is crystallized quickly.

More about Oil shale and Andesite
Here you can know more about Oil shale and Andesite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Oil shale and Andesite consists of mineral content and compound content. 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 Andesite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite, Magnetite, Plagioclase, Pyroxene, Zircon. You can also check out the list of all Sedimentary Rocks. When we have to compare Oil shale vs Andesite, 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, Andesite is available in bluish - grey, grey, pink, yellow colors. Appearance of Oil shale is Muddy and that of Andesite is Dull and Soft. Properties of rock is another aspect for Oil shale vs Andesite. The hardness of Oil shale is 2-3 and that of Andesite is 7. The types of Oil shale are Carbonate-rich Shale, Siliceous Shale and Cannel Shale whereas types of Andesite are Icelandite.
