Definition
Eclogite is an extreme metamorphic rock, formed by regional metamorphism of basalt rock under very high pressure and temperature
Talc carbonate is nothing but a rock sequence or a mineral composition found in metamorphic ultramafic rocks.

Features
Available in Lots of Colors and Patterns, Generally rough to touch, Is one of the oldest rock
Easily splits into thin plates, Generally rough to touch, Host Rock for Lead
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.
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Talc Carbonate is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

Eclogite vs Talc carbonate 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 Talc carbonate characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Eclogite and Properties of Talc carbonate. Learn more about Eclogite vs Talc carbonate in the next section. The interior uses of Eclogite include Decorative aggregates and Interior decoration whereas the interior uses of Talc carbonate include Decorative aggregates and Interior decoration. Due to some exceptional properties of Eclogite and Talc carbonate, they have various applications in construction industry. The uses of Eclogite in construction industry include and that of Talc carbonate include Source of calcium.
More about Eclogite and Talc carbonate
Here you can know more about Eclogite and Talc carbonate. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Eclogite and Talc carbonate 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 Talc carbonate includes Carbonate, Chlorite, Magnesium. You can also check out the list of all Metamorphic Rocks. When we have to compare Eclogite vs Talc carbonate, 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, Talc carbonate is available in grey, white colors. Appearance of Eclogite is Dull, Banded and Foilated and that of Talc carbonate is Soft. Properties of rock is another aspect for Eclogite vs Talc carbonate. The hardness of Eclogite is 3.5-4 and that of Talc carbonate is 1-2. The types of Eclogite are Eclogite whereas types of Talc carbonate are Sedimentary rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Eclogite and Talc carbonate is white. The specific heat capacity of Eclogite is 0.75 kJ/Kg K and that of Talc carbonate is 0.92 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 Talc carbonate is heat resistant, wear resistant.
