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

More about Hornblendite and Flint
Here you can know more about Hornblendite and Flint. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Hornblendite and Flint consists of mineral content and compound content. The mineral content of Hornblendite includes Amphibole, Calcite, Hornblade, Magnetite, Plagioclase, Wollastonite and mineral content of Flint includes Silicon. You can also check out the list of all Igneous Rocks. When we have to compare Hornblendite vs Flint, the texture, color and appearance plays an important role in determining the type of rock. Hornblendite is available in black, brown, green, grey colors whereas, Flint is available in black, brown, green, grey, red, white colors. Appearance of Hornblendite is Foliated and that of Flint is Glassy or Pearly. Properties of rock is another aspect for Hornblendite vs Flint. The hardness of Hornblendite is 6-7 and that of Flint is 7. The types of Hornblendite are Hornblende Gabbro and Hornblende Peridotite whereas types of Flint are Chert and Jasper. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Hornblendite is white to grey while that of Flint is white. The specific heat capacity of Hornblendite is 0.84 kJ/Kg K and that of Flint is 0.74 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Hornblendite is heat resistant, pressure resistant, wear resistant whereas Flint is heat resistant, impact resistant, pressure resistant, wear resistant.
