Formation
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Jadeitite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.
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 Jadeitite and Tuff
Here you can know more about Jadeitite and Tuff. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Jadeitite and Tuff consists of mineral content and compound content. The mineral content of Jadeitite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides and mineral content of Tuff includes Calcite, Chlorite. You can also check out the list of all Metamorphic Rocks. When we have to compare Jadeitite vs Tuff, the texture, color and appearance plays an important role in determining the type of rock. Jadeitite is available in black, brown, colourless, green, grey, white colors whereas, Tuff is available in brown, grey, yellow colors. Appearance of Jadeitite is Rough and Dull and that of Tuff is Dull, Vesicular and Foilated. Properties of rock is another aspect for Jadeitite vs Tuff. The hardness of Jadeitite is 3-5 and that of Tuff is 4-6. The types of Jadeitite 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 Jadeitite and Tuff is white, greenish white or grey. The specific heat capacity of Jadeitite is 0.95 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.Jadeitite is heat resistant, water resistant whereas Tuff is heat resistant, impact resistant, pressure resistant, wear resistant.
