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.
Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.

The uses of Oil shale in construction industry include Cement manufacture, Construction aggregate, For road aggregate, Serves as an oil and gas reservoir rock and that of Basanite include Arrowheads, Construction aggregate, Cutting tool, Spear points.
More about Oil shale and Basanite
Here you can know more about Oil shale and Basanite . The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Oil shale and Basanite 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 Basanite includes Augite, Feldspar, Ilmenite, Olivine, Plagioclase. You can also check out the list of all Sedimentary Rocks. When we have to compare Oil shale vs Basanite , 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, Basanite is available in black, brown, green, grey, red, white colors. Appearance of Oil shale is Muddy and that of Basanite is Glassy or Pearly. Properties of rock is another aspect for Oil shale vs Basanite . The hardness of Oil shale is 2-3 and that of Basanite is 7. The types of Oil shale are Carbonate-rich Shale, Siliceous Shale and Cannel Shale whereas types of Basanite are Nepheline-Basanite, Analcite-Basanite and Leucite-Basanite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Oil shale and Basanite is white. The specific heat capacity of Oil shale is 0.39 kJ/Kg K and that of Basanite is 0.74 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 Basanite is heat resistant, impact resistant, pressure resistant, wear resistant.
