Definition
Diamictite is a sedimentary rock that consists of non-sorted to poorly sorted terrigenous sediment containing particles that range in size from clay to boulders, suspended in a matrix of mudstone or sandstone
Migmatite is typically a granitic rock within a metamorphic host rock which is composed of two intermingled but distinguishable components

Formation
Diamictite is unevenly sorted terrigenous, non-calcareous sedimentary rock which forms due to weathering of mudstone and sandstone.
Migmatites form by high temperature regional and thermal metamorphism of protolith rocks where rocks melt partially due to high temperature.

Diamictite 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. Diamictite vs Migmatite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Diamictite and Properties of Migmatite. Learn more about Diamictite vs Migmatite in the next section. The interior uses of Diamictite include Decorative aggregates and Interior decoration whereas the interior uses of Migmatite include Countertops, Flooring and Kitchens. Due to some exceptional properties of Diamictite and Migmatite, they have various applications in construction industry. The uses of Diamictite in construction industry include As dimension stone, Construction aggregate, For road aggregate, Landscaping, Roadstone and that of Migmatite include As dimension stone, Cement manufacture, For road aggregate, Making natural cement.
More about Diamictite and Migmatite
Here you can know more about Diamictite and Migmatite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diamictite and Migmatite consists of mineral content and compound content. The mineral content of Diamictite includes Calcite, Clay, Feldspar, Micas, 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 Diamictite vs Migmatite, the texture, color and appearance plays an important role in determining the type of rock. Diamictite is available in brown, buff colors whereas, Migmatite is available in black, bluish - grey, brown, brown- black, dark greenish - grey, dark grey to black colors. Appearance of Diamictite is Banded and that of Migmatite is Dull, Banded and Foilated. Properties of rock is another aspect for Diamictite vs Migmatite. The hardness of Diamictite is 2-3 and that of Migmatite is 5.5-6.5. The types of Diamictite are Bedded Diamictite and Laminated Diamictite 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 Diamictite is light to dark brown while that of Migmatite is white. The specific heat capacity of Diamictite is 0.75 kJ/Kg K and that of Migmatite is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Diamictite is heat resistant, impact resistant whereas Migmatite is heat resistant, pressure resistant.
