Formation
Theralite 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.
Whiteschist is formed by dynamic metamorphism at high temperatures and pressures that aligns the grains of mica, hornblende and other elongated minerals into thin layers.

More about Theralite and Whiteschist
Here you can know more about Theralite and Whiteschist. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Theralite and Whiteschist consists of mineral content and compound content. The mineral content of Theralite includes Augite, Olivine, Plagioclase, Pyroxene and mineral content of Whiteschist includes Carbonate, Coesite, Quartz, Silica. You can also check out the list of all Igneous Rocks. When we have to compare Theralite vs Whiteschist, the texture, color and appearance plays an important role in determining the type of rock. Theralite is available in dark grey to black colors whereas, Whiteschist is available in colourless, green, grey, white colors. Appearance of Theralite is Veined and Shiny and that of Whiteschist is Banded and Foilated. Properties of rock is another aspect for Theralite vs Whiteschist. The hardness of Theralite is 7 and that of Whiteschist is 1.5. The types of Theralite are Teschenite and Essexite whereas types of Whiteschist are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Theralite and Whiteschist is white. The specific heat capacity of Theralite is 0.74 kJ/Kg K and that of Whiteschist 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.Theralite is impact resistant, pressure resistant, wear resistant whereas Whiteschist is heat resistant.
