Definition
Shoshonite is a basaltic rock, properly a potassic trachyandesite, composed of olivine, augite and plagioclase phenocrysts in a groundmass with calcic plagioclase and sanidine and some dark-colored volcanic glass
Whiteschist is an uncommon rock type belonging to a class of metamorphic rock, this is formed at high-ultra-high pressures

Archaeological Significance
Formation
Shoshonite 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 Shoshonite and Whiteschist
Here you can know more about Shoshonite and Whiteschist. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Shoshonite and Whiteschist consists of mineral content and compound content. The mineral content of Shoshonite includes 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 Shoshonite vs Whiteschist, the texture, color and appearance plays an important role in determining the type of rock. Shoshonite is available in brown- black, dark brown colors whereas, Whiteschist is available in green, grey, white colors. Appearance of Shoshonite is Dull and that of Whiteschist is Banded and Foilated. Properties of rock is another aspect for Shoshonite vs Whiteschist. The hardness of Shoshonite is 6 and that of Whiteschist is 1.5. The types of Shoshonite are Intermediate volcanic rock whereas types of Whiteschist are -. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Shoshonite is white to grey while that of Whiteschist is white. The specific heat capacity of Shoshonite is 0.79 kJ/Kg K and that of Whiteschist is 0.92 kJ/Kg K.
