Formation
Dacitic magma is formed by the subduction of young oceanic crust under a thick felsic continental plate. Further, the Oceanic crust is hydrothermally altered as quartz and sodium are added.
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 Dacite and Sandstone
Here you can know more about Dacite and Sandstone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Dacite and Sandstone consists of mineral content and compound content. The mineral content of Dacite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Magnetite, Plagioclase, Pyroxene, Quartz, Zircon and mineral content of Sandstone includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz. You can also check out the list of all . When we have to compare Dacite vs Sandstone, the texture, color and appearance plays an important role in determining the type of rock. Dacite is available in bluish - grey, brown, grey, light to dark grey colors whereas, Sandstone is available in beige, black, brown, colourless, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors. Appearance of Dacite is Vesicular and that of Sandstone is Rough. Properties of rock is another aspect for Dacite vs Sandstone. The hardness of Dacite is 2-2.25 and that of Sandstone is 6-7. The types of Dacite are Footwall Dacite, Hanging wall Dacite, Tuff and Biotite Dacite 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 Dacite and Sandstone is white. The specific heat capacity of Dacite is 0.92 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.Dacite is heat resistant, impact resistant, pressure resistant, wear resistant whereas Sandstone is heat resistant, impact resistant, pressure resistant.
