Definition
Migmatite is typically a granitic rock within a metamorphic host rock which is composed of two intermingled but distinguishable components
A sedimentary rock, deposit of a submarine turbidity currents and are composed of layered particles
Origin
Southern Alps, France
European Foreland Basins

Etymology
From the Greek word migma which means a mixture
From Medieval Latin turbiditas, from Latin turbidus (turbid). Turbidity current is from 1939

Formation
Migmatites form by high temperature regional and thermal metamorphism of protolith rocks where rocks melt partially due to high temperature.
Turbidite is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. These particles then settle down and are subjected to high temperature and pressures hence forming Turbidite.

More about Migmatite and Turbidite
Here you can know more about Migmatite and Turbidite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Migmatite and Turbidite 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 Turbidite includes Coesite, Quartz, Sand. You can also check out the list of all Metamorphic Rocks. When we have to compare Migmatite vs Turbidite, 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, Turbidite is available in black, brown, colourless, green, grey, pink colors. Appearance of Migmatite is Dull, Banded and Foilated and that of Turbidite is Dull and Banded. Properties of rock is another aspect for Migmatite vs Turbidite. The hardness of Migmatite is 5.5-6.5 and that of Turbidite is 3. The types of Migmatite are Diatexites and Metatexites whereas types of Turbidite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Migmatite is white while that of Turbidite is white, greenish white or grey. The specific heat capacity of Migmatite is Not Available and that of Turbidite 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 Turbidite is heat resistant.
