Archaeological Significance
Formation
Phonolite are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.

Phonolite vs Enderbite 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. Phonolite vs Enderbite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Phonolite and Properties of Enderbite. Learn more about Phonolite vs Enderbite in the next section. The interior uses of Phonolite include Countertops, Decorative aggregates, Flooring and Homes whereas the interior uses of Enderbite include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Homes, Hotels, Kitchens and Stair treads. Due to some exceptional properties of Phonolite and Enderbite, they have various applications in construction industry. The uses of Phonolite in construction industry 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 and that of Enderbite include As dimension stone.
More about Phonolite and Enderbite
Here you can know more about Phonolite and Enderbite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Phonolite and Enderbite consists of mineral content and compound content. The mineral content of Phonolite includes Albite, Amphibole, Biotite, Cancrinite, Feldspar, Hornblende, Plagioclase, Pyroxene, Sodalite and mineral content of Enderbite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Phonolite vs Enderbite, the texture, color and appearance plays an important role in determining the type of rock. Phonolite is available in brown, buff, cream, green, grey, pink, white colors whereas, Enderbite is available in black, grey, orange, pink, white colors. Appearance of Phonolite is Banded and Foilated and that of Enderbite is Veined or Pebbled. Properties of rock is another aspect for Phonolite vs Enderbite. The hardness of Phonolite is 5.5-6 and that of Enderbite is 6-7. The types of Phonolite are Kenyte whereas types of Enderbite are -. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Phonolite and Enderbite is white. The specific heat capacity of Phonolite is 0.84 kJ/Kg K and that of Enderbite is 0.79 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Phonolite is heat resistant, impact resistant, wear resistant whereas Enderbite is heat resistant, wear resistant.
