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

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

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