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

Phonolite vs Jasperoid 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 Jasperoid characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Phonolite and Properties of Jasperoid. Learn more about Phonolite vs Jasperoid in the next section. The interior uses of Phonolite include Countertops, Decorative aggregates, Flooring and Homes whereas the interior uses of Jasperoid include Decorative aggregates, Floor tiles, Homes and Interior decoration. Due to some exceptional properties of Phonolite and Jasperoid, 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 Jasperoid include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories, Production of glass and ceramics, Serves as an oil and gas reservoir rock.
More about Phonolite and Jasperoid
Here you can know more about Phonolite and Jasperoid. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Phonolite and Jasperoid 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 Jasperoid includes Clay Minerals, Pyrite, Quartz, Sulfides. You can also check out the list of all Igneous Rocks. When we have to compare Phonolite vs Jasperoid, 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, Jasperoid is available in black, brown, colourless, green, grey, pink, white colors. Appearance of Phonolite is Banded and Foilated and that of Jasperoid is Glassy or Pearly. Properties of rock is another aspect for Phonolite vs Jasperoid. The hardness of Phonolite is 5.5-6 and that of Jasperoid is 3.5-4. The types of Phonolite are Kenyte whereas types of Jasperoid are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Phonolite and Jasperoid is white. The specific heat capacity of Phonolite is Not Available and that of Jasperoid is 0.92 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 Jasperoid is heat resistant, pressure resistant, wear resistant.
