Definition
Eclogite is an extreme metamorphic rock, formed by regional metamorphism of basalt rock under very high pressure and temperature
Aplite is a fine-grained granite composed mainly of feldspar and quartz

Archaeological Significance
Formation
Eclogite forms from high-pressure metamorphism of mafic igneous rocks mainly, basalt or gabbro as it plunges into the mantle in a subduction zone.
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.

Eclogite vs Aplite 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. Eclogite vs Aplite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Eclogite and Properties of Aplite. Learn more about Eclogite vs Aplite in the next section. The interior uses of Eclogite include Decorative aggregates and Interior decoration whereas the interior uses of Aplite include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Homes, Hotels, Kitchens and Stair treads. Due to some exceptional properties of Eclogite and Aplite, they have various applications in construction industry. The uses of Eclogite in construction industry include and that of Aplite include As dimension stone.
More about Eclogite and Aplite
Here you can know more about Eclogite and Aplite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Eclogite and Aplite consists of mineral content and compound content. The mineral content of Eclogite includes Amphibole, Coesite, Corundum, Dolomite, Garnet, Kyanite, Lawsonite, Paragonite, Phengite, Pyroxene, Quartz, Rutile, Zoisite and mineral content of Aplite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Eclogite vs Aplite, the texture, color and appearance plays an important role in determining the type of rock. Eclogite is available in black, brown, green, grey, pink, white colors whereas, Aplite is available in black, grey, orange, pink, white colors. Appearance of Eclogite is Dull, Banded and Foilated and that of Aplite is Veined or Pebbled. Properties of rock is another aspect for Eclogite vs Aplite. The hardness of Eclogite is 3.5-4 and that of Aplite is 6.5. The types of Eclogite are Eclogite whereas types of Aplite are Igneous rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Eclogite and Aplite is white. The specific heat capacity of Eclogite is 0.75 kJ/Kg K and that of Aplite is 0.79 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Eclogite is heat resistant whereas Aplite is heat resistant, wear resistant.
