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
Theralite is a plutonic hylocrystalline igneous rock consisting of augite, olivine, calcic plagioclase and nepheline

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.
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.

More about Shoshonite and Theralite
Here you can know more about Shoshonite and Theralite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Shoshonite and Theralite consists of mineral content and compound content. The mineral content of Shoshonite includes Pyroxene and mineral content of Theralite includes Augite, Olivine, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Shoshonite vs Theralite, 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, Theralite is available in dark grey to black colors. Appearance of Shoshonite is Dull and that of Theralite is Veined and Shiny. Properties of rock is another aspect for Shoshonite vs Theralite. The hardness of Shoshonite is 6 and that of Theralite is 7. The types of Shoshonite are Not Available whereas types of Theralite are Teschenite and Essexite. 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 Theralite is white. The specific heat capacity of Shoshonite is Not Available and that of Theralite is 0.74 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Shoshonite is heat resistant, pressure resistant whereas Theralite is impact resistant, pressure resistant, wear resistant.
