Archaeological Significance
Formation
Aplites belong to intrusive igneous rocks which are mostly quart and alkali feldspar and are formed from residual eutectic granitic liquids and represent the final crystallization products of magma.
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.

Aplite 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. Aplite vs Oil shale characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Aplite and Properties of Oil shale. Learn more about Aplite vs Oil shale in the next section. The interior uses of Aplite include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Homes, Hotels, Kitchens and Stair treads whereas the interior uses of Oil shale include . Due to some exceptional properties of Aplite and Oil shale, they have various applications in construction industry. The uses of Aplite 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 Aplite and Oil shale
Here you can know more about Aplite and Oil shale. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Aplite and Oil shale consists of mineral content and compound content. The mineral content of Aplite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz 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 Aplite vs Oil shale, the texture, color and appearance plays an important role in determining the type of rock. Aplite 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 Aplite is Veined or Pebbled and that of Oil shale is Muddy. Properties of rock is another aspect for Aplite vs Oil shale. The hardness of Aplite is 6.5 and that of Oil shale is 2-3. The types of Aplite are Igneous rock 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 Aplite and Oil shale is white. The specific heat capacity of Aplite 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.Aplite is heat resistant, wear resistant whereas Oil shale is heat resistant, impact resistant.
