Definition
Claystone is a fine-grained, dark gray to pink sedimentary rock which mainly consists of compacted and hardened clay
Migmatite is typically a granitic rock within a metamorphic host rock which is composed of two intermingled but distinguishable components

Features
Available in Lots of Colors and Patterns, Smooth to touch, Very fine grained rock
Generally rough to touch, Is one of the oldest rock
Archaeological Significance
Formation
Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.
Migmatites form by high temperature regional and thermal metamorphism of protolith rocks where rocks melt partially due to high temperature.

Claystone vs Migmatite 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. Claystone vs Migmatite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Claystone and Properties of Migmatite. Learn more about Claystone vs Migmatite in the next section. The interior uses of Claystone include Decorative aggregates, Entryways, Floor tiles, Homes and Interior decoration whereas the interior uses of Migmatite include Countertops, Flooring and Kitchens. Due to some exceptional properties of Claystone and Migmatite, they have various applications in construction industry. The uses of Claystone in construction industry include As a sintering agent in steel industry to process iron ore, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar and that of Migmatite include As dimension stone, Cement manufacture, For road aggregate, Making natural cement.
More about Claystone and Migmatite
Here you can know more about Claystone and Migmatite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Claystone and Migmatite consists of mineral content and compound content. The mineral content of Claystone includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz and mineral content of Migmatite includes Biotite, Chlorite, Feldspar, Garnet, Graphite, Hornblade, Micas, Muscovite or Illite, Quartz, Quartzite, Silica, Zircon. You can also check out the list of all Sedimentary Rocks. When we have to compare Claystone vs Migmatite, the texture, color and appearance plays an important role in determining the type of rock. Claystone is available in black, blue, brown, green, grey, orange, red, white, yellow colors whereas, Migmatite is available in black, bluish - grey, brown, brown- black, dark greenish - grey, dark grey to black colors. Appearance of Claystone is Rough and Dull and that of Migmatite is Dull, Banded and Foilated. Properties of rock is another aspect for Claystone vs Migmatite. The hardness of Claystone is 3.5-4 and that of Migmatite is 5.5-6.5. The types of Claystone are Claystone whereas types of Migmatite are Diatexites and Metatexites. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Claystone and Migmatite is white. The specific heat capacity of Claystone is 0.92 kJ/Kg K and that of Migmatite is 0.79 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Claystone is heat resistant, impact resistant whereas Migmatite is heat resistant, pressure resistant.
