Definition
Theralite is a plutonic hylocrystalline igneous rock consisting of augite, olivine, calcic plagioclase and nepheline
Sandstone is defined as a rock which is composed of sand-sized grains of various minerals mostly of uniform size and often are smooth and rounded

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.
Sandstone is a sedimentary rock which forms from cemented sand-sized clasts. It forms when sand layers are buried under sediments of sand.

More about Theralite and Sandstone
Here you can know more about Theralite and Sandstone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Theralite and Sandstone consists of mineral content and compound content. The mineral content of Theralite includes Augite, Olivine, Plagioclase, Pyroxene and mineral content of Sandstone includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Theralite vs Sandstone, 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, Sandstone is available in beige, black, brown, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors. Appearance of Theralite is Veined and Shiny and that of Sandstone is Rough. Properties of rock is another aspect for Theralite vs Sandstone. The hardness of Theralite is 7 and that of Sandstone is 6-7. The types of Theralite are Teschenite and Essexite whereas types of Sandstone are Grey Sandstones, Crystallized Sandstones, Hard Sandstones , Carbonate Cemented Sandstones and Ganister. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Theralite and Sandstone is white. The specific heat capacity of Theralite is 0.74 kJ/Kg K and that of Sandstone 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 Sandstone is heat resistant, impact resistant, pressure resistant.
