Definition
Gabbro is an intrusive igneous rock which is chemically equivalent to plutonic Basalt
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
Gabbro, a mafic rock, forms due to cooling and crystallization of magma underneath Earth's surface.
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 Gabbro and Sandstone
Here you can know more about Gabbro and Sandstone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Gabbro and Sandstone consists of mineral content and compound content. The mineral content of Gabbro 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 Gabbro vs Sandstone, the texture, color and appearance plays an important role in determining the type of rock. Gabbro 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 Gabbro is Veined and Shiny and that of Sandstone is Rough. Properties of rock is another aspect for Gabbro vs Sandstone. The hardness of Gabbro is 7 and that of Sandstone is 6-7. The types of Gabbro are Anorthosite Gabbro and Norite Gabbro 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 Gabbro is black while that of Sandstone is white. The specific heat capacity of Gabbro is 0.71 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.Gabbro is impact resistant, pressure resistant, wear resistant whereas Sandstone is heat resistant, impact resistant, pressure resistant.
