Definition
Wehrlite is an ultramafic and ultrabasic rock that is a mixture of olivine and clinopyroxene. It is a subdivision of the peridotites
Flint is a hard type of sedimentary rock that produces a small piece of burning material when hit by steel

Archaeological Significance
Formation
Wehrlite 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 Wehrlite and Flint
Here you can know more about Wehrlite and Flint. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Wehrlite and Flint consists of mineral content and compound content. The mineral content of Wehrlite includes Pyroxene and mineral content of Flint includes Silicon. You can also check out the list of all Igneous Rocks. When we have to compare Wehrlite vs Flint, the texture, color and appearance plays an important role in determining the type of rock. Wehrlite is available in dark greenish - grey, green colors whereas, Flint is available in black, brown, green, grey, red, white colors. Appearance of Wehrlite is Rough and Banded and that of Flint is Glassy or Pearly. Properties of rock is another aspect for Wehrlite vs Flint. The hardness of Wehrlite is 5.5-6 and that of Flint is 7. The types of Wehrlite are Ultramafic rock 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 Wehrlite and Flint is white. The specific heat capacity of Wehrlite is 0.63 kJ/Kg K and that of Flint is 0.74 kJ/Kg K.
