Definition
Adamellite is a coarse-grained porphyritic igneous rock, a variety of Monzogranite and dominated by phenocrysts of orthoclase in a granular groundmass of perthite, plagioclase and quartz
Tuff is a type of rock made of volcanic ash ejected from a vent during a volcanic eruption

Formation
Adamellite is a type of Igneous rock which is formed through the cooling and solidification of lava or magma and is a variety of Monzogranite.
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.

More about Adamellite and Tuff
Here you can know more about Adamellite and Tuff. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Adamellite and Tuff consists of mineral content and compound content. The mineral content of Adamellite includes Apatite, Biotite, Chlorite, Orthoclase, Perthite, Plagioclase, Quartz, Titanite, Zircon and mineral content of Tuff includes Calcite, Chlorite. You can also check out the list of all Igneous Rocks. When we have to compare Adamellite vs Tuff, the texture, color and appearance plays an important role in determining the type of rock. Adamellite is available in black, grey, orange, pink, white colors whereas, Tuff is available in brown, grey, yellow colors. Appearance of Adamellite is Veined or Pebbled and that of Tuff is Dull, Vesicular and Foilated. Properties of rock is another aspect for Adamellite vs Tuff. The hardness of Adamellite is 6-7 and that of Tuff is 4-6. The types of Adamellite are Not Available 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 Adamellite and Tuff is white. The specific heat capacity of Adamellite is 0.79 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.Adamellite is heat resistant, wear resistant whereas Tuff is heat resistant, impact resistant, pressure resistant, wear resistant.
