Definition
Migmatite is typically a granitic rock within a metamorphic host rock which is composed of two intermingled but distinguishable components
A carbonate rock which is matrix supported and contains over 10% allochems in a carbonate mud matrix.

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

Migmatite vs Wackestone 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 Wackestone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Migmatite and Properties of Wackestone. Learn more about Migmatite vs Wackestone in the next section. The interior uses of Migmatite include Countertops, Flooring and Kitchens whereas the interior uses of Wackestone include Decorative aggregates, Flooring and Interior decoration. Due to some exceptional properties of Migmatite and Wackestone, 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 Wackestone include Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar.
More about Migmatite and Wackestone
Here you can know more about Migmatite and Wackestone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Migmatite and Wackestone 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 Wackestone 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 Wackestone, 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, Wackestone is available in black, blue, brown, green, grey, orange, red, white, yellow colors. Appearance of Migmatite is Dull, Banded and Foilated and that of Wackestone is Rough and Dull. Properties of rock is another aspect for Migmatite vs Wackestone. The hardness of Migmatite is 5.5-6.5 and that of Wackestone is 2-3. The types of Migmatite are Diatexites and Metatexites whereas types of Wackestone are Marl, Shale and Argillite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Migmatite and Wackestone is white. The specific heat capacity of Migmatite is 0.79 kJ/Kg K and that of Wackestone is 0.39 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 Wackestone is heat resistant, impact resistant.
