Definition
Flint is a hard type of sedimentary rock that produces a small piece of burning material when hit by steel
Kenyte is a variety of porphyritic phonolite or trachyte rock with rhomb shaped phenocrysts of anorthoclase with variable olivine and augite in a glassy matrix

Archaeological Significance
Formation
Flint is formed by the decomposition and compaction of various organisms such as sponges and diatoms under the water.
Kenyte 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.

More about Flint and Kenyte
Here you can know more about Flint and Kenyte. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Flint and Kenyte consists of mineral content and compound content. The mineral content of Flint includes Silicon and mineral content of Kenyte includes Albite, Amphibole, Biotite, Cancrinite, Feldspar, Hornblende, Plagioclase, Pyroxene, Sodalite. You can also check out the list of all Sedimentary Rocks. When we have to compare Flint vs Kenyte, the texture, color and appearance plays an important role in determining the type of rock. Flint is available in black, brown, green, grey, red, white colors whereas, Kenyte is available in brown, buff, cream, green, grey, pink, white colors. Appearance of Flint is Glassy or Pearly and that of Kenyte is Banded and Foilated. Properties of rock is another aspect for Flint vs Kenyte. The hardness of Flint is 7 and that of Kenyte is 5.5-6. The types of Flint are Chert and Jasper whereas types of Kenyte are Foidolite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface.
