Definition
Eclogite is an extreme metamorphic rock, formed by regional metamorphism of basalt rock under very high pressure and temperature
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

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.
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.

All about Eclogite and Mudstone Properties
Know all about Eclogite and Mudstone properties here. All properties of rocks are important as they define the type of rock and its application. Eclogite belongs to Metamorphic Rocks while Mudstone belongs to Sedimentary Rocks.Texture of Eclogite is Earthy whereas that of Mudstone is Clastic. Eclogite appears Dull, Banded and Foilated and Mudstone appears Rough and Dull. The luster of Eclogite is subvitreous to dull while that of Mudstone is dull. Eclogite is available in black, brown, colourless, green, grey, pink, white colors whereas Mudstone is available in black, blue, brown, green, grey, orange, red, white, yellow colors. The commercial uses of Eclogite are creating artwork, gemstone and that of Mudstone are creating artwork, pottery.
