Formation
Migmatites form by high temperature regional and thermal metamorphism of protolith rocks where rocks melt partially due to high temperature.
Latite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

Migmatite vs Latite 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 Latite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Migmatite and Properties of Latite. Learn more about Migmatite vs Latite in the next section. The interior uses of Migmatite include Countertops, Flooring and Kitchens whereas the interior uses of Latite include Decorative aggregates, Entryways and Interior decoration. Due to some exceptional properties of Migmatite and Latite, 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 Latite include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories.
More about Migmatite and Latite
Here you can know more about Migmatite and Latite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Migmatite and Latite 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 Latite includes Alkali feldspar, Biotite, Plagioclase, Pyroxene. You can also check out the list of all Metamorphic Rocks. When we have to compare Migmatite vs Latite, 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, Latite is available in black, brown, colourless, green, grey, pink, white colors. Appearance of Migmatite is Dull, Banded and Foilated and that of Latite is Rough. Properties of rock is another aspect for Migmatite vs Latite. The hardness of Migmatite is 5.5-6.5 and that of Latite is 5-5.5. The types of Migmatite are Diatexites and Metatexites whereas types of Latite are Rhomb porphyries. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Migmatite and Latite is white. The specific heat capacity of Migmatite is Not Available and that of Latite 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 Latite is heat resistant, pressure resistant.
