Definition
Mudstone is a fine-grained, dark gray sedimentary rock, which is formed from silt and clay and is similar to shale but has less laminations
Eclogite is an extreme metamorphic rock, formed by regional metamorphism of basalt rock under very high pressure and temperature

Archaeological Significance
Formation
Mudstone forms when very fine-grained clay particles are deposited in water which settle at the bottom of water bodies. They are buried and compacted by overlying sediment hence forming mudstone.
Eclogite forms from high-pressure metamorphism of mafic igneous rocks mainly, basalt or gabbro as it plunges into the mantle in a subduction zone.

More about Mudstone and Eclogite
Here you can know more about Mudstone and Eclogite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Mudstone and Eclogite consists of mineral content and compound content. The mineral content of Mudstone includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz and mineral content of Eclogite includes Amphibole, Coesite, Corundum, Dolomite, Garnet, Kyanite, Lawsonite, Paragonite, Phengite, Pyroxene, Quartz, Rutile, Zoisite. You can also check out the list of all Sedimentary Rocks. When we have to compare Mudstone vs Eclogite, the texture, color and appearance plays an important role in determining the type of rock. Mudstone is available in black, blue, brown, green, grey, orange, red, white, yellow colors whereas, Eclogite is available in black, brown, green, grey, pink, white colors. Appearance of Mudstone is Rough and Dull and that of Eclogite is Dull, Banded and Foilated. Properties of rock is another aspect for Mudstone vs Eclogite. The hardness of Mudstone is 2-3 and that of Eclogite is 3.5-4. The types of Mudstone are Marl, Shale and Argillite whereas types of Eclogite are Eclogite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Mudstone and Eclogite is white. The specific heat capacity of Mudstone is 0.39 kJ/Kg K and that of Eclogite is 0.75 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Mudstone is heat resistant, impact resistant whereas Eclogite is heat resistant.
