Definition
Kenyte is a variety of porphyritic phonolite or trachyte rock with rhomb shaped phenocrysts of anorthoclase with variable olivine and augite in a glassy matrix
It is a metamorphic magnesium rich rock because it is composed of the mineral talc

Etymology
From the mountain ranges- Mount Kenya and is named by J. W. Gregory in 1900
From 17th century, because of its greasy feel and use like a soap

Formation
Kenyte 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.
Soapstone is a talc-schist, which is a type of metamorphic rock and it is largely composed of the mineral talc and is thus rich inmagnesium.

The mineral content of Kenyte includes Albite, Amphibole, Biotite, Cancrinite, Feldspar, Hornblende, Plagioclase, Pyroxene, Sodalite and mineral content of Soapstone includes Albite, Apatite, Biotite, Calcite, Carbonate, Clay Minerals, Hornblende, Ilmenite, Micas, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Kenyte vs Soapstone, the texture, color and appearance plays an important role in determining the type of rock. Kenyte is available in brown, buff, cream, green, grey, pink, white colors whereas, Soapstone is available in black, black to grey, green, grey colors. Appearance of Kenyte is Banded and Foilated and that of Soapstone is Dull, Banded and Foilated. Properties of rock is another aspect for Kenyte vs Soapstone. The hardness of Kenyte is 5.5-6 and that of Soapstone is 1. The types of Kenyte are Foidolite whereas types of Soapstone are Metamorphic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Kenyte is white, greenish white or grey while that of Soapstone is black. The specific heat capacity of Kenyte is 0.84 kJ/Kg K and that of Soapstone is 0.88 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Kenyte is heat resistant, impact resistant, wear resistant whereas Soapstone is heat resistant, pressure resistant.
