Definition
Lherzolite is a type of ultramafic igneous rock which contains essential olivine and clinopyroxene and orthopyroxene in equal proportions
Phonolite is an uncommon extrusive igneous rock volcanic rock of intermediate chemical composition between felsic and mafic

Etymology
From the Lherz Massif, an alpine peridotite complex, at Étang de Lers, near Massat in the French Pyrenees; Lherz is the archaic spelling of this location
From the Greek meaning sounding stone because of the metallic sound it produces if an unfractured plate is hit

Archaeological Significance
Formation
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.
Phonolite are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.

Lherzolite vs Phonolite Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Lherzolite vs Phonolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Lherzolite and Properties of Phonolite. Learn more about Lherzolite vs Phonolite in the next section. The interior uses of Lherzolite include Decorative aggregates, Entryways, Homes and Interior decoration whereas the interior uses of Phonolite include Countertops, Decorative aggregates, Flooring and Homes. Due to some exceptional properties of Lherzolite and Phonolite, they have various applications in construction industry. The uses of Lherzolite in construction industry include Landscaping, Manufacture of magnesium and dolomite refractories, Used for flooring, stair treads, borders and window sills. and that of Phonolite include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Landscaping, Making natural cement, Manufacture of magnesium and dolomite refractories, Production of glass and ceramics.
More about Lherzolite and Phonolite
Here you can know more about Lherzolite and Phonolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Lherzolite and Phonolite consists of mineral content and compound content. The mineral content of Lherzolite includes Harzburgite, Olivine, Pyroxene, Pyrrhotite and mineral content of Phonolite includes Albite, Amphibole, Biotite, Cancrinite, Feldspar, Hornblende, Plagioclase, Pyroxene, Sodalite. You can also check out the list of all Igneous Rocks. When we have to compare Lherzolite vs Phonolite, the texture, color and appearance plays an important role in determining the type of rock. Lherzolite is available in black, dark greenish - grey, green, pink, purple colors whereas, Phonolite is available in brown, buff, cream, green, grey, pink, white colors. Appearance of Lherzolite is Glassy, Vesicular and Foilated and that of Phonolite is Banded and Foilated. Properties of rock is another aspect for Lherzolite vs Phonolite. The hardness of Lherzolite is 6.5 and that of Phonolite is 5.5-6. The types of Lherzolite are Garnet Lherzolite whereas types of Phonolite are Kenyte. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Lherzolite and Phonolite is white. The specific heat capacity of Lherzolite is 0.95 kJ/Kg K and that of Phonolite is 0.84 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Lherzolite is heat resistant, impact resistant, pressure resistant, wear resistant whereas Phonolite is heat resistant, impact resistant, wear resistant.
