Definition

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

Tuff is a type of rock made of volcanic ash ejected from a vent during a volcanic eruption

History

Etymology

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

From a Latin word tophous then in Italian tufo and finally tuff

Formation

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

Tuff is formed when large masses of ash and sand which are mixed with hot gases are ejected by a volcano and avalanche rapidly down its slopes.

Conglomerate vs Tuff 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 Conglomerate and Tuff Reserves. Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix. Tuff is a type of rock made of volcanic ash ejected from a vent during a volcanic eruption. 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 Conglomerate vs Tuff information and Conglomerate vs Tuff characteristics in the upcoming sections.

More about Conglomerate and Tuff

Here you can know more about Conglomerate and Tuff. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Conglomerate and Tuff consists of mineral content and compound content. The mineral content of Conglomerate includes Clay, Sand, Silica, Silt and mineral content of Tuff includes Calcite, Chlorite. You can also check out the list of all Sedimentary Rocks. When we have to compare Conglomerate vs Tuff, 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, Tuff is available in brown, grey, yellow colors. Appearance of Conglomerate is Shiny and Rounded and that of Tuff is Dull, Vesicular and Foilated. Properties of rock is another aspect for Conglomerate vs Tuff. The hardness of Conglomerate is 2-3 and that of Tuff is 4-6. The types of Conglomerate are Orthoconglomerate and Paraconglomerate whereas types of Tuff are Welded tuff, Rhyolitic tuff, Basaltic tuff, Trachyte tuff, Andesitic tuff and Ignimbrite.. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Conglomerate and Tuff is white. The specific heat capacity of Conglomerate is 0.92 kJ/Kg K and that of Tuff is 0.20 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 Tuff is heat resistant, impact resistant, pressure resistant, wear resistant.
