Definition
Basanite is a black basaltic rock which mainly contains plagioclase, augite, olivine and nepheline and is formerly used as a touchstone
Lherzolite is a type of ultramafic igneous rock which contains essential olivine and clinopyroxene and orthopyroxene in equal proportions

Formation
Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
Lherzolite 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 Lherzolite
Here you can know more about Basanite and Lherzolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Basanite and Lherzolite consists of mineral content and compound content. The mineral content of Basanite includes Augite, Feldspar, Ilmenite, Olivine, Plagioclase and mineral content of Lherzolite includes Harzburgite, Olivine, Pyroxene, Pyrrhotite. You can also check out the list of all . When we have to compare Basanite vs Lherzolite, 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, Lherzolite is available in black, dark greenish - grey, green, pink, purple colors. Appearance of Basanite is Glassy or Pearly and that of Lherzolite is Glassy, Vesicular and Foilated. Properties of rock is another aspect for Basanite vs Lherzolite. The hardness of Basanite is 7 and that of Lherzolite is 6.5. The types of Basanite are Nepheline-Basanite, Analcite-Basanite and Leucite-Basanite whereas types of Lherzolite are Garnet Lherzolite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Basanite and Lherzolite is white. The specific heat capacity of Basanite is 0.74 kJ/Kg K and that of Lherzolite is 0.95 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Basanite is heat resistant, impact resistant, pressure resistant, wear resistant whereas Lherzolite is heat resistant, impact resistant, pressure resistant, wear resistant.
