Formation
Sandstone is a sedimentary rock which forms from cemented sand-sized clasts. It forms when sand layers are buried under sediments of sand.
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 Sandstone and Theralite
Here you can know more about Sandstone and Theralite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Sandstone and Theralite consists of mineral content and compound content. The mineral content of Sandstone includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz and mineral content of Theralite includes Augite, Olivine, Plagioclase, Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Sandstone vs Theralite, the texture, color and appearance plays an important role in determining the type of rock. Sandstone is available in beige, black, brown, colourless, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors whereas, Theralite is available in dark grey to black colors. Appearance of Sandstone is Rough and that of Theralite is Veined and Shiny. Properties of rock is another aspect for Sandstone vs Theralite. The hardness of Sandstone is 6-7 and that of Theralite is 7. The types of Sandstone are Grey Sandstones, Crystallized Sandstones, Hard Sandstones , Carbonate Cemented Sandstones and Ganister 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 Sandstone and Theralite is white. The specific heat capacity of Sandstone is 0.92 kJ/Kg K 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.Sandstone is heat resistant, impact resistant, pressure resistant whereas Theralite is impact resistant, pressure resistant, wear resistant.
