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
Marble is a non-foliated metamorphic rock which is composed of recrystallized carbonate which is formed when limestone is exposed to high temperatures and pressures over a long time

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.
Marble is a metamorphic rock produced from limestone in the earth crust. It is formed by the metamorphism of limestone.

All about Mudstone and Marble Properties
Know all about Mudstone and Marble properties here. All properties of rocks are important as they define the type of rock and its application. Mudstone belongs to Sedimentary Rocks while Marble belongs to Metamorphic Rocks.Texture of Mudstone is Clastic whereas that of Marble is Granular. Mudstone appears Rough and Dull and Marble appears Veined and Shiny. The luster of Mudstone is dull while that of Marble is dull to pearly to subvitreous. Mudstone is available in black, blue, brown, green, grey, orange, red, white, yellow colors whereas Marble is available in black, blue, brown, grey, pink, white colors.
