Archaeological Significance
Formation
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.
Gabbro, a mafic rock, forms due to cooling and crystallization of magma underneath Earth's surface.

Conglomerate vs Gabbro Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Conglomerate vs Gabbro characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Conglomerate and Properties of Gabbro. Learn more about Conglomerate vs Gabbro in the next section. The interior uses of Conglomerate include Decorative aggregates, Floor tiles and Homes whereas the interior uses of Gabbro include Countertops, Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Conglomerate and Gabbro, they have various applications in construction industry. The uses of Conglomerate in construction industry include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Roadstone and that of Gabbro include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate.
More about Conglomerate and Gabbro
Here you can know more about Conglomerate and Gabbro. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Conglomerate and Gabbro consists of mineral content and compound content. The mineral content of Conglomerate includes Clay, Sand, Silica, Silt and mineral content of Gabbro includes Augite, Olivine, Plagioclase, Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Conglomerate vs Gabbro, the texture, color and appearance plays an important role in determining the type of rock. Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors whereas, Gabbro is available in dark grey to black colors. Appearance of Conglomerate is Shiny and Rounded and that of Gabbro is Veined and Shiny. Properties of rock is another aspect for Conglomerate vs Gabbro. The hardness of Conglomerate is 2-3 and that of Gabbro is 7. The types of Conglomerate are Orthoconglomerate and Paraconglomerate whereas types of Gabbro are Anorthosite Gabbro and Norite Gabbro. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Conglomerate is white while that of Gabbro is black. The specific heat capacity of Conglomerate is 0.92 kJ/Kg K and that of Gabbro is 0.71 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Conglomerate is heat resistant whereas Gabbro is impact resistant, pressure resistant, wear resistant.
