Definition
Adamellite is a coarse-grained porphyritic igneous rock, a variety of Monzogranite and dominated by phenocrysts of orthoclase in a granular groundmass of perthite, plagioclase and quartz
Oil Shale is a fine-grained sedimentary rock from which oil is extracted

Formation
Adamellite is a type of Igneous rock which is formed through the cooling and solidification of lava or magma and is a variety of Monzogranite.
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.

Adamellite vs Oil shale Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Adamellite vs Oil shale characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Adamellite and Properties of Oil shale. Learn more about Adamellite vs Oil shale in the next section. The interior uses of Adamellite include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Homes, Hotels, Kitchens and Stair treads whereas the interior uses of Oil shale include Not yet used. Due to some exceptional properties of Adamellite and Oil shale, they have various applications in construction industry. The uses of Adamellite in construction industry include As dimension stone and that of Oil shale include Cement manufacture, Construction aggregate, For road aggregate, Serves as an oil and gas reservoir rock.
More about Adamellite and Oil shale
Here you can know more about Adamellite and Oil shale. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Adamellite and Oil shale consists of mineral content and compound content. The mineral content of Adamellite includes Apatite, Biotite, Chlorite, Orthoclase, Perthite, Plagioclase, Quartz, Titanite, Zircon and mineral content of Oil shale includes Albite, Biotite, Calcite, Chert, Chlorite, Dolomite, Hematite, Micas, Muscovite or Illite, Pyrite, Quartz, Silica, Sulfides. You can also check out the list of all Igneous Rocks. When we have to compare Adamellite vs Oil shale, the texture, color and appearance plays an important role in determining the type of rock. Adamellite is available in black, grey, orange, pink, white colors whereas, Oil shale is available in black, brown, buff, green, grey, red, yellow colors. Appearance of Adamellite is Veined or Pebbled and that of Oil shale is Muddy. Properties of rock is another aspect for Adamellite vs Oil shale. The hardness of Adamellite is 6-7 and that of Oil shale is 2-3. The types of Adamellite are Not Available whereas types of Oil shale are Carbonate-rich Shale, Siliceous Shale and Cannel Shale. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Adamellite and Oil shale is white. The specific heat capacity of Adamellite is 0.79 kJ/Kg K and that of Oil shale is 0.39 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Adamellite is heat resistant, wear resistant whereas Oil shale is heat resistant, impact resistant.
