Definition
Eclogite is an extreme metamorphic rock, formed by regional metamorphism of basalt rock under very high pressure and temperature
Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix

Etymology
From French, Greek eklogē selection with reference to the selective content of the rock + -ite1
From Latin conglomeratus, to roll together, i.e. from com together + glomerare to gather into a ball, from glomus (genitive glomeris) a ball

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.
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.

Eclogite vs Conglomerate 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 Conglomerate characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Eclogite and Properties of Conglomerate. Learn more about Eclogite vs Conglomerate in the next section. The interior uses of Eclogite include Decorative aggregates and Interior decoration whereas the interior uses of Conglomerate include Decorative aggregates, Floor tiles and Homes. Due to some exceptional properties of Eclogite and Conglomerate, they have various applications in construction industry. The uses of Eclogite in construction industry include and that of Conglomerate include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Roadstone.
More about Eclogite and Conglomerate
Here you can know more about Eclogite and Conglomerate. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Eclogite and Conglomerate 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 Conglomerate includes Clay, Sand, Silica, Silt. You can also check out the list of all Metamorphic Rocks. When we have to compare Eclogite vs Conglomerate, 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, Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors. Appearance of Eclogite is Dull, Banded and Foilated and that of Conglomerate is Shiny and Rounded. Properties of rock is another aspect for Eclogite vs Conglomerate. The hardness of Eclogite is 3.5-4 and that of Conglomerate is 2-3. The types of Eclogite are Eclogite whereas types of Conglomerate are Orthoconglomerate and Paraconglomerate. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Eclogite and Conglomerate is white. The specific heat capacity of Eclogite is 0.75 kJ/Kg K and that of Conglomerate 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 Conglomerate is heat resistant.
