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.
Jasperoid is a rare and peculiar type of metasomatic alteration of rocks. It is formed by extreme alteration of wall rocks within a shear zone which may occur in sediments, andesites, trachytes and basalts.

More about Wehrlite and Jasperoid
Here you can know more about Wehrlite and Jasperoid. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Wehrlite and Jasperoid consists of mineral content and compound content. The mineral content of Wehrlite includes Pyroxene and mineral content of Jasperoid includes Clay Minerals, Pyrite, Quartz, Sulfides. You can also check out the list of all Igneous Rocks. When we have to compare Wehrlite vs Jasperoid, 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, Jasperoid is available in black, brown, green, grey, pink, white colors. Appearance of Wehrlite is Rough and Banded and that of Jasperoid is Glassy or Pearly. Properties of rock is another aspect for Wehrlite vs Jasperoid. The hardness of Wehrlite is 5.5-6 and that of Jasperoid is 3.5-4. The types of Wehrlite are Ultramafic rock whereas types of Jasperoid are -. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Wehrlite and Jasperoid is white.
