Archaeological Significance
Formation
Migmatites form by high temperature regional and thermal metamorphism of protolith rocks where rocks melt partially due to high temperature.
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Jadeitite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

More about Migmatite and Jadeitite
Here you can know more about Migmatite and Jadeitite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Migmatite and Jadeitite 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 Jadeitite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides. You can also check out the list of all Metamorphic Rocks. When we have to compare Migmatite vs Jadeitite, 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, Jadeitite is available in black, brown, green, grey, white colors. Appearance of Migmatite is Dull, Banded and Foilated and that of Jadeitite is Rough and Dull. Properties of rock is another aspect for Migmatite vs Jadeitite. The hardness of Migmatite is 5.5-6.5 and that of Jadeitite is 3-5. The types of Migmatite are Diatexites and Metatexites whereas types of Jadeitite are Metamorphic rock. 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 Jadeitite is white, greenish white or grey. The specific heat capacity of Migmatite is 0.79 kJ/Kg K and that of Jadeitite is 0.95 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 Jadeitite is heat resistant, water resistant.
