Definition
Oil Shale is a fine-grained sedimentary rock from which oil is extracted
Marble is a non-foliated metamorphic rock which is composed of recrystallized carbonate which is formed when limestone is exposed to high temperatures and pressures over a long time

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.
Marble is a metamorphic rock produced from limestone in the earth crust. It is formed by the metamorphism of limestone.

More about Oil shale and Marble
Here you can know more about Oil shale and Marble. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Oil shale and Marble 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 Marble includes Garnet, Graphite, Olivine, Pyrite, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Oil shale vs Marble, 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, Marble is available in black, blue, brown, grey, pink, white colors. Appearance of Oil shale is Muddy and that of Marble is Veined and Shiny. Properties of rock is another aspect for Oil shale vs Marble. The hardness of Oil shale is 2-3 and that of Marble is 3-4. The types of Oil shale are Carbonate-rich Shale, Siliceous Shale and Cannel Shale whereas types of Marble are Breccia Marble, Carrara Marble, Calacatta marble, Cultured Marble, Polished Marble, Honed Marble, Sand Marble. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Oil shale and Marble is white. The specific heat capacity of Oil shale is 0.39 kJ/Kg K and that of Marble is 0.88 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 Marble is heat resistant.
