Definition
Flint is a hard type of sedimentary rock that produces a small piece of burning material when hit by steel
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.

Archaeological Significance
Formation
Flint is formed by the decomposition and compaction of various organisms such as sponges and diatoms under the water.
Suevite is a metamorphic rock consisting partly of melted material, typically forming a breccia containing glass and crystal or lithic fragments, formed during an impact event.

Due to some exceptional properties of Flint and Suevite, they have various applications in construction industry. The uses of Flint in construction industry include Arrowheads, Cutting tool, Spear points and that of Suevite include As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories.
More about Flint and Suevite
Here you can know more about Flint and Suevite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Flint and Suevite consists of mineral content and compound content. The mineral content of Flint includes Silicon and mineral content of Suevite includes Coesite, Quartz, Stishovite. You can also check out the list of all Sedimentary Rocks. When we have to compare Flint vs Suevite, 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, Suevite is available in black, brown, green, grey, pink colors. Appearance of Flint is Glassy or Pearly and that of Suevite is Banded. Properties of rock is another aspect for Flint vs Suevite. The hardness of Flint is 7 and that of Suevite is 5.5. The types of Flint are Chert and Jasper whereas types of Suevite are Phyllosilicates, Calcite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Flint is white while that of Suevite is light to dark brown. The specific heat capacity of Flint is 0.74 kJ/Kg K and that of Suevite 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.Flint is heat resistant, impact resistant, pressure resistant, wear resistant whereas Suevite is heat resistant.
