Archaeological Significance
Formation
Itacolumite is a sedimentary rock which forms from cemented sand-sized clasts and is a type of sandstone.
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.

More about Itacolumite and Wehrlite
Here you can know more about Itacolumite and Wehrlite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Itacolumite and Wehrlite consists of mineral content and compound content. The mineral content of Itacolumite includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz and mineral content of Wehrlite includes Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Itacolumite vs Wehrlite, the texture, color and appearance plays an important role in determining the type of rock. Itacolumite is available in beige, black, brown, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors whereas, Wehrlite is available in dark greenish - grey, green colors. Appearance of Itacolumite is Rough and that of Wehrlite is Rough and Banded. Properties of rock is another aspect for Itacolumite vs Wehrlite. The hardness of Itacolumite is 6-7 and that of Wehrlite is 5.5-6. The types of Itacolumite are Sandstone whereas types of Wehrlite are Ultramafic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Itacolumite and Wehrlite is white.
