Definition

Basalt is a common extrusive igneous rock formed by the rapid cooling of basaltic lava exposed at or very near the surface of Earth

Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix

Etymology

From Late Latin Basaltes (variant of basanites ), very hard stone, which was imported from Ancient Greek Basanites

From Latin conglomeratus, to roll together, i.e. from com together + glomerare to gather into a ball, from glomus (genitive glomeris) a ball

Formation

Basalt forms when lava reaches the Earth's surface near an active volcano. The temperature of lava is between 1100 to 1250° C when it gets to the surface.

Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.

Basalt vs Conglomerate Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Basalt and Conglomerate Reserves. Basalt is a common extrusive igneous rock formed by the rapid cooling of basaltic lava exposed at or very near the surface of Earth. Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Basalt vs Conglomerate information and Basalt vs Conglomerate characteristics in the upcoming sections.

More about Basalt and Conglomerate

Here you can know more about Basalt and Conglomerate. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Basalt and Conglomerate consists of mineral content and compound content. The mineral content of Basalt includes Olivine, Plagioclase, Pyroxene and mineral content of Conglomerate includes Clay, Sand, Silica, Silt. You can also check out the list of all Igneous Rocks. When we have to compare Basalt vs Conglomerate, the texture, color and appearance plays an important role in determining the type of rock. Basalt is available in black, brown, light to dark grey colors whereas, Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors. Appearance of Basalt is Dull and Soft and that of Conglomerate is Shiny and Rounded. Properties of rock is another aspect for Basalt vs Conglomerate. The hardness of Basalt is 6 and that of Conglomerate is 2-3. The types of Basalt are Alkaline Basalt, Boninite, High Alumina Basalt, Mid Ocean Ridge Basalt (MORB), Tholeiitic Basalt, Basaltic trachyandesite, Mugearite and Shoshonite whereas types of Conglomerate are Orthoconglomerate and Paraconglomerate. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Basalt is white to grey while that of Conglomerate is white. The specific heat capacity of Basalt is 0.84 kJ/Kg K and that of Conglomerate 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.Basalt is heat resistant, pressure resistant, wear resistant whereas Conglomerate is heat resistant.
