Definition

Phonolite is an uncommon extrusive igneous rock volcanic rock of intermediate chemical composition between felsic and mafic

Kimberlite is a rare, blue-tinged, coarse-grained intrusive igneous rock, which sometimes contains diamonds and is mostly found in South Africa and Siberia.

History

Origin

Kimberley, South Africa

Discoverer

John W. Judd

Etymology

From the Greek meaning sounding stone because of the metallic sound it produces if an unfractured plate is hit

From Kimberley +‎ -ite, from the name of the South African town of Kimberley where the rock was first found.

Formation

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

Kimberlite is an igneous rock and is the main source of diamonds. Its formation takes place deep beneath the Earth’s surface between 150 to 450 kilometres, and are erupted rapidly and violently.

You can also check out the list of all Igneous Rocks. When we have to compare Phonolite vs Kimberlite, 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, Kimberlite is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors. Appearance of Phonolite is Banded and Foilated and that of Kimberlite is Dull and Banded. Properties of rock is another aspect for Phonolite vs Kimberlite. The hardness of Phonolite is 5.5-6 and that of Kimberlite is 6-7. The types of Phonolite are Kenyte whereas types of Kimberlite are Basaltic Kimberlites and Micaceous Kimberlites. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Phonolite and Kimberlite is white. The specific heat capacity of Phonolite is 0.84 kJ/Kg K and that of Kimberlite 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 Kimberlite is heat resistant, impact resistant.
