Archaeological Significance
Formation
Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
Harzburgite 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 Basanite and Harzburgite
Here you can know more about Basanite and Harzburgite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Basanite and Harzburgite consists of mineral content and compound content. The mineral content of Basanite includes Augite, Feldspar, Ilmenite, Olivine, Plagioclase and mineral content of Harzburgite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Basanite vs Harzburgite, the texture, color and appearance plays an important role in determining the type of rock. Basanite is available in black, brown, green, grey, red, white colors whereas, Harzburgite is available in dark greenish - grey colors. Appearance of Basanite is Glassy or Pearly and that of Harzburgite is Rough and Shiny. Properties of rock is another aspect for Basanite vs Harzburgite. The hardness of Basanite is 7 and that of Harzburgite is 5.5-6. The types of Basanite are Nepheline-Basanite, Analcite-Basanite and Leucite-Basanite whereas types of Harzburgite are Ultramafic rock.
