Formation
Ignimbrites are formed from very poorly sorted mixture of volcanic ash or tuff and pumice lapilli, commonly with scattered lithic fragments.
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.

More about Ignimbrite and Jadeitite
Here you can know more about Ignimbrite and Jadeitite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Ignimbrite and Jadeitite consists of mineral content and compound content. The mineral content of Ignimbrite includes Apatite, Biotite, Calcite, Chlorite, Feldspar, Hematite, Hornblade, Ilmenite, Magnetite, Olivine, Pyroxene, Quartz and mineral content of Jadeitite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides. You can also check out the list of all Igneous Rocks. When we have to compare Ignimbrite vs Jadeitite, the texture, color and appearance plays an important role in determining the type of rock. Ignimbrite is available in beige, black, brown, grey, pink, white colors whereas, Jadeitite is available in black, brown, colourless, green, grey, white colors. Appearance of Ignimbrite is Dull, Vesicular and Foilated and that of Jadeitite is Rough and Dull. Properties of rock is another aspect for Ignimbrite vs Jadeitite. The hardness of Ignimbrite is 4-6 and that of Jadeitite is 3-5. The types of Ignimbrite are Not Available whereas types of Jadeitite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Ignimbrite is white while that of Jadeitite is white, greenish white or grey. The specific heat capacity of Ignimbrite is 0.20 kJ/Kg K and that of Jadeitite is 0.95 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Ignimbrite is heat resistant, impact resistant, pressure resistant, wear resistant whereas Jadeitite is heat resistant, water resistant.
