Definition
Minette is a variety of Lamprophyre and is porphyritic alkaline igneous rock which is mainly dominated by biotite and potassic feldspar
Flint is a hard type of sedimentary rock that produces a small piece of burning material when hit by steel

Features
Always found as volcanic pipes over deep continental crust, Host rock for Diamond, Is one of the oldest rock, Surfaces are often shiny
Clasts are smooth to touch, Easily splits into thin plates, Has High structural resistance against erosion and climate
Archaeological Significance
Formation
Minette formation takes place deep beneath the Earth’s surface at around 150 to 450 kms, and are erupted rapidly and violently.
Flint is formed by the decomposition and compaction of various organisms such as sponges and diatoms under the water.

More about Minette and Flint
Here you can know more about Minette and Flint. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Minette and Flint consists of mineral content and compound content. The mineral content of Minette includes Amphibole, Carbonate, Garnet, Micas, Olivine, Phlogopite, Pyroxene and mineral content of Flint includes Silicon. You can also check out the list of all Igneous Rocks. When we have to compare Minette vs Flint, the texture, color and appearance plays an important role in determining the type of rock. Minette is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors whereas, Flint is available in black, brown, green, grey, red, white colors. Appearance of Minette is Dull, Banded and Foilated and that of Flint is Glassy or Pearly. Properties of rock is another aspect for Minette vs Flint. The hardness of Minette is 5-6 and that of Flint is 7. The types of Minette are Minette, Alnoite, Camptonite, Monchiquite, Fourchite, Vogesite, Appinite and Spessartite whereas types of Flint are Chert and Jasper.
